Hitory of The Love Story of Abelard and Heloise

The love story of Abelard and Heliose has endured as one of the famous and popular love stories of all times.  It is the tale of a French philospher named Peter Abelard (1079-1142), one of the greatest thinkers of the Middle Ages, but because his teachings were controversial, he soon was accused of heresy.


Heliose ( 1101- 1164) was a well educated niece of a prominent cleric named Canon Fulbert.  It was through Canon Fulbert that Heloise and Abelard met.

In 1117 Abelard went to live at the house of Canon Fulbert of the Cathedral of Notre Dam as a border.  The moment he laid eyes on Heloise, he was intrigued by her beauty and intelligence.  He wanted to get to know her more so he convinced Canon Fulbert to let him tutor Heloise. Abelard was twenty years her senior.


The two fell in love and before long, Heliose found herself pregnant.  Abelard wanted to marry Heloise even though he would lose his job.  But Heloise refused his suit, citing that their marriage would impede his work because it would bring disgrace upon him. But Abelard refused to give up.  After much persistence, he convinced her to marry him in secret.  Heloise gave birth to their son.  Abelard hated keeping his marriage and new family a secret and he longed to tell Canon Fulbert regardless of the risk to his career.  Yet, he kept the secret.  Canon Fulbert somehow learned about their marriage.  Enraged that Abelard has ruined his niece, Fulbert sent some unsavory men to break into Abelard's quarters and castrate him. Once he recovered, in humiliation, Abelard entered the Abbey of St Denis and took his vows as a monk.  Heartbroken, and knowing in her heart that she wanted no other man, Heloise left her son with her sister and became a nun, despite Abelard's protestations. In her convent, she rose in rank due to her literacy and ability to manage.

Catherine Benincasa of Siena (1347 - 1380) History

I was born in Siena on the feast of the Annunciation, in the year 1347. I, and my twin sister who did not long survive, were the youngest of twenty-five children. My father, Giacomo Benincasa, was a prosperous wool dyer, and lived with my mother Lapa and our extended family, in a spacious house which the Sienese have preserved to the present day.

As a child, I was so merry that the family gave me the pet name of Euphrosyne, which is Greek for Joy and also the name of an early Christian saint.  At the age of six I had the remarkable experience which may be said to have determined my vocation.  With my brother, I was on the way home from a visit to a married sister, when suddenly I stopped still in the road, gazing up into the sky.  I did not hear the repeated calls of the boy, who had walked on ahead.  Only after he had gone back and seized me by the hand did I wake as from a dream.  I burst into tears.  My vision of Christ seated in glory with the Apostles Peter, Paul, and John had faded.  A year later, I made a secret vow to give my whole life to God.  I loved prayer and solitude, and when I mingled with other children it was to teach them.  This made me happy. 


When Catherine I was twelve, my mother, with marriage in mind, began to urge me to pay more attention to my appearance.  To please my mother and sister, I dressed in the bright gowns and jewels that were fashionable for young girls.  Soon I repented of this vanity, and declared with finality that I would never marry.  When my parents persisted in their talk about finding me a husband, I cut off the golden-brown hair that was my chief beauty.  As punishment, I was now made to do menial work in the household, and my family, knowing I craved solitude, never allowed me to be alone.  I bore all this with sweetness and patience.  Long afterwards, I wrote that God had shown me how to build in my soul a private cell where no tribulation could enter.


My father at last came to the realization that further pressure was useless, and he permitted me to do as I pleased.  In a small, dimly-lighted room now set apart for my use, a cell nine feet by three, I gave myself up to prayers and fasting.  I scourged myself three times daily with an iron chain, and slept on a board.  At first I wore a hair shirt, subsequently replacing it by an iron-spiked girdle.  Soon I obtained what I ardently desired, permission to assume the black habit of a Dominican tertiary, which was customarily granted only to matrons or widows.  I now increased my asceticism, eating and sleeping very little.  For three years I spoke only to my confessor and never went out except to the neighboring Basilica of Saint Dominic, where the pillar against which I used to lean is still pointed out to visitors.

History of Romeo and juuliet

Add caption
Romeo and Juliet is an enduring tragic love story written by William Shakespeare about two young star-crossed lovers whose deaths ultimately unite their feuding families. Shakespeare borrowed his plot from an original Italian tale.  It is believed Romeo and Juliette were based on actual characters from Verona.

The Montague and Capulet families are feuding.  The Prince of Verona intervenes and declares that any further fighting will be punishable by death.

When the Count of Paris approaches Lord Capulet about marrying his daughter, Juliet, he is wary of the request because she is only thirteen.  Capulet asks the Count of Paris to wait another two years and invites him to attend a ball.  Lady Capulet and Juliet's nurse urge Juliet to accept Paris' courtship.

In the Montague house, Benvolio talks with his cousin Romeo, Lord Montague's son, about Romeo's recent melancholy.  Benvolio discovers Romeo's unrequited infatuation for a girl named Rosaline, a niece of Lord Capulet's nieces.  Persuaded by Benvolio Romeo attends the ball at the Capulet house in hopes of meeting Rosaline.  But it is not Rosaline who sweeps him off his feet - it is the fair Juliette.

history of Windows

A history of Windows

Highlights from the first 25 years
1975–1981: Microsoft boots up
Getting started: Microsoft co-founders Paul Allen (left) and Bill Gates Getting started: Microsoft co-founders Paul Allen (left) and Bill Gates

It’s the 1970s. At work, we rely on typewriters. If we need to copy a document, we likely use a mimeograph or carbon paper. Few have heard of microcomputers, but two young computer enthusiasts, Bill Gates and Paul Allen, see that personal computing is a path to the future.

In 1975, Gates and Allen form a partnership called Microsoft. Like most start-ups, Microsoft begins small, but has a huge vision—a computer on every desktop and in every home. During the next years, Microsoft begins to change the ways we work.
The dawn of MS‑DOS

In June 1980, Gates and Allen hire Gates’ former Harvard classmate Steve Ballmer to help run the company. The next month, IBM approaches Microsoft about a project code-named "Chess." In response, Microsoft focuses on a new operating system—the software that manages, or runs, the computer hardware and also serves to bridge the gap between the computer hardware and programs, such as a word processor. It’s the foundation on which computer programs can run. They name their new operating system "MS‑DOS."

When the IBM PC running MS‑DOS ships in 1981, it introduces a whole new language to the general public. Typing “C:” and various cryptic commands gradually becomes part of daily work. People discover the backslash (\) key.

MS‑DOS is effective, but also proves difficult to understand for many people. There has to be a better way to build an operating system.

Geek trivia: MS‑DOS stands for Microsoft Disk Operating System.

1982–1985: Introducing Windows 1.0
The Windows 1.0 desktop
Microsoft works on the first version of a new operating system. Interface Manager is the code name and is considered as the final name, but Windows prevails because it best describes the boxes or computing “windows” that are fundamental to the new system. Windows is announced in 1983, but it takes a while to develop. Skeptics call it “vaporware.”
The fully-packaged Windows 1.0 The fully-packaged Windows 1.0
On November 20, 1985, two years after the initial announcement, Microsoft ships Windows 1.0. Now, rather than typing MS‑DOS commands, you just move a mouse to point and click your way through screens, or “windows.” Bill Gates says, “It is unique software designed for the serious PC user…”

There are drop-down menus, scroll bars, icons, and dialog boxes that make programs easier to learn and use. You're able to switch among several programs without having to quit and restart each one. Windows 1.0 ships with several programs, including MS‑DOS file management, Paint, Windows Writer, Notepad, Calculator, and a calendar, card file, and clock to help you manage day-to-day activities. There’s even a game—Reversi.

Geek trivia: Remember floppy disks and kilobytes? Windows 1.0 requires a minimum of 256 kilobytes (KB), two double-sided floppy disk drives, and a graphics adapter card. A hard disk and 512 KB memory is recommended for running multiple programs or when using DOS 3.0 or higher.


1987–1992: Windows 2.0–2.11—More windows, more speed
The Windows 2.0 desktopOn December 9, 1987 Microsoft releases Windows 2.0 with desktop icons and expanded memory. With improved graphics support, you can now overlap windows, control the screen layout, and use keyboard shortcuts to speed up your work. Some software developers write their first Windows–based programs for this release.
Windows 2.0 Windows 2.0

Windows 2.0 is designed for the Intel 286 processor. When the Intel 386 processor is released, Windows/386 soon follows to take advantage of its extended memory capabilities. Subsequent Windows releases continue to improve the speed, reliability, and usability of the PC.

In 1988, Microsoft becomes the world’s largest PC software company based on sales. Computers are starting to become a part of daily life for some office workers.


Geek trivia: Control Panel makes its first appearance in Windows 2.0.

1990–1994: Windows 3.0–Windows NT—Getting the graphics
The Windows 3.0 desktop

On May 22, 1990, Microsoft announces Windows 3.0, followed shortly by Windows 3.1 in 1992. Taken together, they sell 10 million copies in their first 2 years, making this the most widely used Windows operating system yet. The scale of this success causes Microsoft to revise earlier plans. Virtual Memory improves visual graphics. In 1990 Windows starts to look like the versions to come.

Windows now has significantly better performance, advanced graphics with 16 colors, and improved icons. A new wave of 386 PCs helps drive the popularity of Windows 3.0. With full support for the Intel 386 processor, programs run noticeably faster. Program Manager, File Manager, and Print Manager arrive in Windows 3.0.

Windows software is installed with floppy discs bought in large boxes with heavy instruction manuals.

The popularity of Windows 3.0 grows with the release of a new Windows software development kit (SDK), which helps software developers focus more on writing programs and less on writing device drivers.

Windows is increasingly used at work and home and now includes games like Solitaire, Hearts, and Minesweeper. An advertisement: “Now you can use the incredible power of Windows 3.0 to goof off.”

Windows for Workgroups 3.11 adds peer-to-peer workgroup and domain networking support and, for the first time, PCs become an integral part of the emerging client/server computing evolution.
Windows NT

When Windows NT releases on July 27, 1993, Microsoft meets an important milestone: the completion of a project begun in the late 1980s to build an advanced new operating system from scratch. "Windows NT represents nothing less than a fundamental change in the way that companies can address their business computing requirements," Bill Gates says at its release.

Unlike Windows 3.1, however, Windows NT 3.1 is a 32-bit operating system, which makes it a strategic business platform that supports high-end engineering and scientific programs.

Geek trivia: The group that develops Windows NT was originally called the "Portable Systems" team.

1995–2001: Windows 95—the PC comes of age (and don't forget the Internet)
The Windows 95 desktop

On August 24, 1995, Microsoft releases Windows 95, selling a record-setting 7 million copies in the first five weeks. It’s the most publicized launch Microsoft has ever taken on. Television commercials feature the Rolling Stones singing "Start Me Up" over images of the new Start button. The press release simply begins: “It’s here.”
Launch day: Bill Gates introduces Windows 95 Launch day: Bill Gates introduces Windows 95

This is the era of fax/modems, e‑mail, the new online world, and dazzling multimedia games and educational software. Windows 95 has built-in Internet support, dial-up networking, and new Plug and Play capabilities that make it easy to install hardware and software. The 32-bit operating system also offers enhanced multimedia capabilities, more powerful features for mobile computing, and integrated networking.

At the time of the Windows 95 release, the previous Windows and MS‑DOS operating systems are running on about 80 percent of the world’s PCs. Windows 95 is the upgrade to these operating systems. To run Windows 95, you need a PC with a 386DX or higher processor (486 recommended) and at least 4 MB of RAM (8 MB of RAM recommended). Upgrade versions are available for both floppy disk and CD-ROM formats. It’s available in 12 languages.


Windows 95 features the first appearance of the Start menu, taskbar, and minimize, maximize, and close buttons on each window.
Catching the Internet wave

In the early 1990s, tech insiders are talking about the Internet—a network of networks that has the power to connect computers all over the world. In 1995, Bill Gates delivers a memo titled “The Internet Tidal Wave,” and declares the Internet as “the most important development since the advent of the PC.”

In the summer of 1995, the first version of Internet Explorer is released. The browser joins those already vying for space on the World Wide Web.

Geek trivia: In 1996, Microsoft releases Flight Simulator for Windows 95—the first time in its 14-year history that it’s available for Windows.
1998–2000: Windows 98, Windows 2000, Windows Me
Windows 98
The Windows 98 desktop

Released on June 25, 1998, Windows 98 is the first version of Windows designed specifically for consumers. PCs are common at work and home, and Internet cafes where you can get online are popping up. Windows 98 is described as an operating system that “Works Better, Plays Better.”

With Windows 98, you can find information more easily on your PC as well as the Internet. Other improvements include the ability to open and close programs more quickly, and support for reading DVD discs and universal serial bus (USB) devices. Another first appearance is the Quick Launch bar, which lets you run programs without having to browse the Start menu or look for them on the desktop.

Geek trivia: Windows 98 is the last version based on MS‑DOS.

brazil empire history

history of brazil empire
The reign of Pedro II, lasting practically a half century, constitutes perhaps the most interesting and fruitful epoch in Brazilian history. The prestige and progress of the nation were due largely to the enlightened statesmanship of its ruler. Though not without personal distinction he was always simple, modest, and democratic. He possessed an insatiable intellectual curiosity and was never happier than when conversing with scholars. He was generous and magnanimous to a fault. One of his favourite occupations was inspecting schools. He was wont to declare, "If I were not emperor I should like to be a schoolteacher." Yet this kindly, genial, and scholarly ruler took his prerogatives and duties as sovereign with great seriousness, and in all matters of first importance he was the final arbiter. According to the moderative power granted to the executive under the constitution of 1824, the emperor had the right to dissolve the Chamber of Deputies, to select the members of the life senate from triple lists submitted by the province, and to appoint and dismiss ministers of state. A kind of parliamentary government functioned under the watchful eye of the Emperor.

Pedro's government took a keen interest in the affairs of the Plata republics, especially of Uruguay, which it sought to control through indirect measures. Brazil aided in the overthrow of the Argentine dictator Juan Manuel de Rosas in 1852. In 1864 Brazil intervened in Uruguayan internal affairs, precipitating war with Paraguay. In alliance with Argentina and Uruguay, Brazil successfully waged the costly and bloody Paraguayan War of 1864-70, eventually overthrowing the Paraguayan dictator Francisco Solano López. This war of the Triple Alliance was the longest and bloodiest war in South American history, and its consequences in Brazil were profound. The empire's relations with the United States and with Europe were generally cordial, Pedro personally visiting Europe in 1871, 1876, and 1888 and the United States in 1876.

The empire's major social and economic problems were related to slave-based plantation agriculture. Real political power remained with large rural landholders, who formed the core of the social and economic elite of Brazil. Industrialization was still economically insignificant, and, with the decline of gold mining, agriculture was unrivaled as the source of Brazil's wealth. Cotton, and increasingly after 1840, coffee, competed with sugar as the leading export crop. The rural landholders were largely insulated from the antislavery current of the times. Although manumission was common, and the number of freedmen and their descendants far surpassed the number of slaves in Brazil, the slave owners as a group resisted pressures for the complete abolition of slavery. Partly as a result of pressure from Great Britain, Brazil had agreed to abolish the slave trade in 1831, but it was not until 1851 that slave traffic completely ceased. Agitation to abolish slavery as such began in the 1860s. Pedro was opposed to slavery, but he had to reckon with the slave owners. Yet the ending of slavery internally seemed the next logical step after stemming the importation of slaves. Accordingly, in 1871, the Law of the Free Womb was enacted, declaring free all children born to slaves. The legislation condemned slavery to eventual extinction. But, although agitation subsided briefly, this concession did not satisfy many of the abolitionists. Led by a young lawyer and writer, Joaquim Nabuco de Araújo, they demanded immediate and complete abolition. Nabuco's book O Abolicionismo (1883; Abolitionism) endeavoured to prove that slavery was poisoning the very life of the nation. In 1884 Ceará and Amazonas freed their slaves; in 1885 all slaves over 60 years of age were liberated. Finally, complete emancipation without compensation to the owners was decreed by the Princess Regent in the absence of the Emperor on May 13, 1888. About 700,000 slaves were freed.
The history of the Empire of Brazil began in 1822, with the proclamation of independence, and lasted until 1889, when the Republic was established. At first, the European countries did not recognize the government of D. Pedro I.

The United States through the Monroe Doctrine sided by the autonomy of the American continent, were the first to recognize the political emancipation of Brazil. The Portuguese crown only recognized the independence of Brazil in August 1825, after the intervention of England, which had so many commercial advantages with Brazil. Portugal also received 2 million pounds as compensation.
