As news of the boycott spread, African-American leaders across Montgomery, Alabama’s capital city, began lending their support. Black ministers announced the boycott in church on Sunday, December 4, and the Montgomery Advertiser, a general-interest newspaper, published a front-page article on the planned action. Approximately 40,000 African-American bus riders–the majority of the city’s black bus riders–boycotted the system the next day. On the afternoon of December 5, black leaders met to form the Montgomery Improvement Association (MIA). The group elected Martin Luther King Jr. (1929-68), the 26-year-old-pastor of Montgomery’s Dexter Avenue Baptist Church, as its president, and decided to continue the boycott until the city met its demands.
