April 9, 1947

1947The Glazier–Higgins–Woodward tornadoes kill 181 and injure 970 in Texas, Oklahoma, and Kansas.^[†]

From April 9–11, 1947, a significant tornado outbreak produced catastrophic effects over portions of the southern Great Plains, in the contiguous United States. The outbreak generated at least 12, and possibly 17 or more, tornadoes, many of which were significant. On Wednesday, April 9, a series of related tornadoes spawned by a single supercell, dubbed the Glazier–Higgins–Woodward tornadoes, swept through the U.S. states of Texas, Oklahoma, and Kansas. Most of the damage and nearly all of the deaths are still blamed on one large tornado, known as the Glazier–Higgins–Woodward tornado, that traveled 98 mi (158 km) from Texas to Oklahoma, beginning over the South Plains. This event, up to nearly 2 mi (3.2 km) in width, was often compared to the Tri-State tornado, because it was originally thought to have left a 198-to-221-mile-long path, was similarly large and intense for much of its path, and was also retroactively rated F5 on the modern-day Fujita scale, but it is now believed to have been part of a 125-to-170-mile-long family of nine or 10 tornadoes.

1947The Journey of Reconciliation, the first interracial Freedom Ride begins through the upper South in violation of Jim Crow laws. The riders wanted enforcement of the United States Supreme Court's 1946 Irene Morgan decision that banned racial segregation in interstate travel.^[†]

The Journey of Reconciliation, also called "First Freedom Ride", was a form of nonviolent direct action to challenge state segregation laws on interstate buses in the Southern United States. Bayard Rustin and 18 other men and women were the early organizers of the two-week journey that began on April 9, 1947. The participants started their journey in Washington, D.C., traveled as far south as North Carolina, before returning to Washington, D.C.
