The Carolingian Empire covered much of the Western and Central Europe but it collapsed in less than hundred years after the death of Charlemagne in 814. Several factors led to the fall of the Carolingian Empire. The division of Frankish lands among the male members of the Carolingian dynasty was a major factor. The Carolingians extended their rule over most Western and Central Europe in less than one half of a century and became regarded as the renewers of the Roman Empire after the Imperial coronation of Charlemagne in 800. The Carolingian Empire achieved its greatest territorial extent during the reign of Charlemagne (768-814) who added Lombardy, Saxony, Danubian Plain and Spanish March to the Realm of the Franks. However, Charlemagne’s empire started to decline already under his successor Louis the Pious (814-840) and collapsed by the end of the 9th century.
The Revolution of Texas (October 2, 1835-April 21, 1836) was a revolt by U.S. colonists and Tejanos (Texas Mexicans) to bring up armed resistance to Mexico's centralist rule.
The Texas Revolution, also known as the War of Texas Independence, was fought between Mexico and Texas colonists from October 1835 to April 1836, resulting in Texas' independence from Mexico and the creation of the Republic of Texas (1836-45).
