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).
The Constitution was written during the Philadelphia Convention, which took place from May 25, 1787 to September 17, 1787. The Constitution was signed on September 17, 1787 in the Assembly Room of the Pennsylvania State House. It did not go into effect until June 21, 1788 when nine states ratified it.
