Krum the Horrible (Bulgarian: Крум) was Khan of Bulgaria, from after 796, but before 803, to 814 AD. During his reign the Bulgarian territory doubled in size, spreading from the middle Danube to the Dnieper and from Odrin to the Tatra Mountains. His able and energetic rule brought law and order to Bulgaria and developed the rudiments of state organization.

In c. 805, Krum took advantage of the defeat of the Avar Khaganate to destroy the remainder of the Avars and to expand his authority across the Carpathians over Transylvania and along the Danube into eastern Pannonia. This resulted in the establishment of a common border between the Frankish Empire and Bulgaria, which would have important repercussions for the policy of Krum's successors.

Krum engaged in a policy of territorial expansion. In 807 the Bulgarian forces defeated the Byzantine army in the Struma valley. In 809 Krum besieged and forced the surrender of Serdica (Sofia). This victory provoked the reaction of the Byzantine Emperor Nikephoros I, who proceeded to settle Anatolian populations along the frontier to protect it. He also attempted to retake and refortify Serdica, although this enterprise ultimately failed.

Texas (ⁱ/ˈtɛksəs/) (Alibamu: Teksi ) is the second most populous and the second most extensive of the 50 United States, and the most extensive state of the 48 contiguous United States. The name, based on the Caddo word "Tejas" meaning "friends" or "allies", was applied by the Spanish to the Caddo themselves and to the region of their settlement in East Texas. Located in the South Central United States, Texas shares an international border with the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the south, and borders the US states of New Mexico to the west, Oklahoma to the north, Arkansas to the northeast, and Louisiana to the east. Texas has an area of 268,820 square miles (696,200 km²), and a growing population of 25.7 million residents.

During the Spanish colonial rule, the area was officially known as the Nuevo Reino de Filipinas: La Provincia de Texas. Antonio Margil de Jesús was known to be the first person to use the name in a letter to the Viceroy of Mexico in July 20, 1716. The name was not popularly used in daily speech but often appeared in legal documents until the end of the 1800s.
