"No taxation without representation" is a political slogan that originated in the American Revolution, and which expressed one of the primary grievances of the American colonists against Great Britain.

The October Revolution, officially known as the Great October Socialist Revolution under the Soviet Union, also known as the Bolshevik Revolution, was a revolution in Russia led by the Bolshevik Party of Vladimir Lenin that was instrumental in the larger Russian Revolution of 1917–1923.

 The term Industrial Revolution was first popularized by the English economic historian Arnold Toynbee  to describe Britain's economic development from 1760 to 1840.

Nelson Mandela was a South African anti-apartheid revolutionary, political leader and philanthropist who served as President of South Africa from 1994 to 1999.

The Fatimid Caliphate, an Ismaili Shia caliphate of the 10th to the 12th centuries CE, spanned a large area of North Africa, from the Red Sea in the east to the Atlantic Ocean in the west. The Fatimid dynasty, of Arab origin, ruled territories across the Mediterranean coast of Africa and ultimately made Egypt the center of the caliphate.

At its height, the caliphate included - in addition to Egypt - varying areas of the Maghreb, Sudan, Sicily, the Levant, and the Hijaz.

Fatimid Caliphate came to end in 1171 AD.
