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 Old West
This timeline of the American Old West is a chronology ordered list of events significant to the development of the American West as a region of the United States prior to 1912. The term "American Old West" refers to a vast geographical area and lengthy time period of imprecise boundaries, and historians' definitions vary. The events in this timeline occurred primarily in the portion of the modern continental United States west of the Mississippi River, and mostly in the period between the Louisiana Purchase in 1803 and the admission of the last continental states into the Union in 1912. A small section summarizing early exploration and settlement prior to 1803 is included to provide a foundation for later developments. Rarely, events significant to the history of the West but which occurred within the modern boundaries of Canada and Mexico are included as well.
