Renaissance
Many argue that the ideas characterizing the Renaissance had their origin in late 13th-century Florence, in particular with the writings of Dante Alighieri (1265–1321) and Petrarch (1304–1374), as well as the paintings of Giotto di Bondone (1267–1337). Some writers date the Renaissance quite precisely; one proposed starting point is 1401, when the rival geniuses Lorenzo Ghiberti and Filippo Brunelleschi competed for the contract to build the bronze doors for the Baptistery of the Florence Cathedral (Ghiberti won). Others see more general competition between artists and polymaths such as Brunelleschi, Ghiberti, Donatello, and Masaccio for artistic commissions as sparking the creativity of the Renaissance. Yet it remains much debated why the Renaissance began in Italy, and why it began when it did. Accordingly, several theories have been put forward to explain its origins.
Timeline of the American Revolution
Timeline of the American Revolution — timeline of the political upheaval in the 18th century in which Thirteen Colonies in North America joined together for independence from the British Empire, and after victory in the Revolutionary War combined to form the United States of America. The American Revolution includes political, social, and military aspects. The revolutionary era is generally considered to have begun with the passage of the Stamp Act in 1765 and ended with the ratification of the United States Bill of Rights in 1791. The military phase of the revolution, the American Revolutionary War, lasted from 1775 to 1783.
