Many people in the United States, particularly students, parents and teachers, join forces on Read Across America Day. This nationwide observance coincides with the birthday of Dr Seuss, who is known for writing children’s books.

Texas Independence Day is the celebration of the adoption of the Texas Declaration of Independence on March 2, 1836. With this document signed by 59 people, settlers in Mexican Texas officially declared independence from Mexico and created the Republic of Texas.

The Republic of Texas existed from March 2, 1836, to February 19, 1846. The republic's southern- and western-most boundary with Mexico was under dispute throughout the republic's entire existence. Texas claimed the boundary as the Rio Grande (a.k.a. Río Bravo/Río Bravo del Norte), while Mexico claimed the boundary as the Nueces River. This dispute would later become a trigger for the Mexican–American War of 1846–48. The republic's independence ended with Texas's annexation by the U.S. on December 29, 1845.
