A Slight Demonstration is a 2007 book about the 1864 Civil War Battle of Decatur, a pivotal event in Confederate General John B. Hood's disastrous Tennessee Campaign late in the war, in which a Union force of only 2-5,000 soldiers prevented Hood's 23,000 strong army from crossing the Tennessee River.  It was written by Noel Carpenter, a former Decatur native and Air Force officer.  The book is published by Legacy Books & Letters of Austin, Texas.  It is the first book solely devoted to the Battle of Decatur. On June 20th, 1789, the members of the French Estates-General for the Third Estate, who had begun to call themselves the National Assembly, took the Tennis Court Oath (French: "Serment du Jeu de Paume" ), vowing "not to separate, and to reassemble wherever circumstances require, until the constitution of the kingdom is established."  It was a pivotal event in the early days of the French Revolution.

One of nine teams in the IFL for the 2014 season, the Texas Revolution competed in the United Conference for the second consecutive year.  The team played their home games at the Allen Event Center in Allen, Texas.  Chris Williams returned to the IFL as the Texas Revolution's director of football operations and head coach for 2014.

One of nine teams in the CIF for the 2015 season, the Revolution played their home games at the Allen Event Center in Allen, Texas. The 2013 Texas Revolution season was the team's fourteenth season as a football franchise, fourth in the Indoor Football League (IFL), and first as the "Texas Revolution".  One of just nine teams competing in the IFL for the 2013 season, the Texas Revolution were realigned to the United Conference.

Black Friday (Persian: جمعه سیاه "Jom'e-ye Siyāh") is the name given to 8 September 1978 (17 Shahrivar 1357 Iranian calendar) because of the shootings in Jaleh Square (Persian: میدان ژاله "Meydān-e Jāleh") in Tehran, Iran.  The deaths and the reaction to them has been described as a pivotal event in the Iranian Revolution when any "hope for compromise" between the protest movement and the Mohammad Reza Shah's regime was extinguished. George C. Kimble (alternately spelled Kimbell or Kimball, March 6, 1803 – March 6, 1836) was a defender and officer of the Alamo Mission in San Antonio, who died at the Battle of the Alamo.  Kimble County in the hill country of Texas is named in his honor. The Battle of the Alamo (February 23 – March 6, 1836) was a pivotal event in the Texas Revolution.  Following a 13-day siege, Mexican troops under President General Antonio López de Santa Anna launched an assault on the Alamo Mission near San Antonio de Béxar (modern-day San Antonio, Texas, United States), killing all of the Texian defenders.  Santa Anna's cruelty during the battle inspired many Texians—both Texas settlers and adventurers from the United States—to join the Texian Army.  Buoyed by a desire for revenge, the Texians defeated the Mexican Army at the Battle of San Jacinto, on April 21, 1836, ending the revolution. The Army of the Republic of Texas was the land-based component of the armed forces for the Republic of Texas.  It directly descended from the Texian Army, which was established on October 2, 1835, to fight for independence from Mexico in the Texas Revolution.  The army was provisionally formed from the Consultation in November 1835, and officially established on September 5, 1836, from Article II, Section 5 of the Constitution of the Republic of Texas.  After Texas' annexation by the United States, the Army of the Republic of Texas was merged into the United States Army.  Today, the 141st Infantry Regiment trace their lineage back to the Texas Revolution.
