In 1920, the inaugural season of the National Football League (NFL), 11 veterans of Major League Baseball (MLB) (including George Halas and Jim Thorpe) became the first athletes to accomplish the feat. Since 1970, only seven athletes have done so, including Bo Jackson and Deion Sanders.
The Constitution of the Republic of Texas (1836), the first Anglo-American constitution to govern Texas, was drafted by a convention of fifty-nine delegates who assembled at Washington-on-the-Brazos on March 1, 1836 (see CONVENTION OF 1836).
From 1876 through January 2015, the Texas State Legislature proposed 666 amendments to the state's current constitution. Through November 2014, 663 have gone before Texas voters and 484 of those proposed amendments have been approved by voters and added to the constitution; this is an overall 73 percent approval rate.
