IN: Rosa Louise McCauley Parks (February 4, 1913 - October 24, 2005) was an activist in the civil rights movement best known for her pivotal role in the Montgomery Bus Boycott. The United States Congress has called her "the first lady of civil rights" and "the mother of the freedom movement". On December 1, 1955, in Montgomery, Alabama, Parks refused to obey bus driver James F. Blake's order to give up her seat in the "colored section" to a white passenger, after the whites-only section was filled. Parks was not the first person to resist bus segregation, but the NAACP believed that she was the best candidate for seeing through a court challenge after her arrest for civil disobedience in violating Alabama segregation laws.

In 1900, Montgomery had passed a city ordinance to segregate bus passengers by race. Conductors were empowered to assign seats to achieve that goal. According to the law, no passenger would be required to move or give up their seat and stand if the bus was crowded and no other seats were available. Over time and by custom, however, Montgomery bus drivers adopted the practice of requiring black riders to move when there were no white-only seats left.  The first four rows of seats on each Montgomery bus were reserved for whites. Buses had "colored" sections for black people generally in the rear of the bus, although blacks composed more than 75% of the ridership. The sections were not fixed but were determined by placement of a movable sign. Black people could sit in the middle rows until the white section filled; if more whites needed seats, blacks were to move to seats in the rear, stand, or, if there was no room, leave the bus. Black people could not sit across the aisle in the same row as white people. The driver could move the "colored" section sign, or remove it altogether. If white people were already sitting in the front, black people had to board at the front to pay the fare, then disembark and reenter through the rear door.  For years, the black community had complained that the situation was unfair. Parks said, "My resisting being mistreated on the bus did not begin with that particular arrest. I did a lot of walking in Montgomery."  One day in 1943, Parks boarded a bus and paid the fare. She then moved to her seat but driver James F. Blake told her to follow city rules and enter the bus again from the back door. When Parks exited the vehicle, Blake drove off without her. Parks waited for the next bus, determined never to ride with Blake again.
QUESTION: Wht happened after that edeclaration?
IN: The Maya civilization was a Mesoamerican civilization developed by the Maya peoples, and noted for its hieroglyphic script--the only known fully developed writing system of the pre-Columbian Americas--as well as for its art, architecture, mathematics, calendar, and astronomical system. The Maya civilization developed in an area that encompasses southeastern Mexico, all of Guatemala and Belize, and the western portions of Honduras and El Salvador. This region consists of the northern lowlands encompassing the Yucatan Peninsula, and the highlands of the Sierra Madre, running from the Mexican state of Chiapas, across southern Guatemala and onwards into El Salvador, and the southern lowlands of the Pacific littoral plain. The Archaic period, prior to 2000 BC, saw the first developments in agriculture and the earliest villages.

The Maya developed their first civilization in the Preclassic period. Scholars continue to discuss when this era of Maya civilization began. Maya occupation at Cuello (modern-day Belize) has been carbon dated to around 2600 BC. Settlements were established around 1800 BC in the Soconusco region of the Pacific coast, and the Maya were already cultivating the staple crops of maize, beans, squash, and chili pepper. This period was characterized by sedentary communities and the introduction of pottery and fired clay figurines.  During the Middle Preclassic Period, small villages began to grow to form cities. Nakbe in the Peten department of Guatemala is the earliest well-documented city in the Maya lowlands, where large structures have been dated to around 750 BC. The northern lowlands of Yucatan were widely settled by the Middle Preclassic. By approximately 400 BC, early Maya rulers were raising stelae. A developed script was already being used in Peten by the 3rd century BC. In the Late Preclassic Period, the enormous city of El Mirador grew to cover approximately 16 square kilometres (6.2 sq mi). Although not as large, Tikal was already a significant city by around 350 BC.  In the highlands, Kaminaljuyu emerged as a principal centre in the Late Preclassic. Takalik Abaj and Chocola were two of the most important cities on the Pacific coastal plain, and Komchen grew to become an important site in northern Yucatan. The Late Preclassic cultural florescence collapsed in the 1st century AD and many of the great Maya cities of the epoch were abandoned; the cause of this collapse is unknown.
