The members of the Mamluk ruling class were purchased as slaves (mamluks) and manumitted, with the most powerful among them taking the role of sultan in Cairo. While several Bahri Mamluk sultans tried to establish hereditary dynasties through their sons, these attempts were ultimately unsuccessful, with the role of sultan often passing on to another powerful Mamluk.

Blake is recognised as the "chief founder of England's naval supremacy", a dominance subsequently inherited by the British Royal Navy well into the early 20th century. Despite this, due to deliberate attempts to expunge the Parliamentarians from historical records following the Stuart Restoration, Blake's achievements tend to remain relatively unrecognised. Blake's successes, however, are considered to have "never been excelled, not even by Nelson" according to one biographer, while Blake is often compared with Nelson by others.

It remains among the most infamous massacres in the United States and the deadliest mass shooting in Colorado.

A 6.6-magnitude earthquake strikes Lushan County, Ya'an, in China's Sichuan province, killing at least 193 people and injuring thousands.

Measure of earthquake size

The moment magnitude scale is a measure of an earthquake's magnitude based on its seismic moment. Mw was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori. Similar to the local magnitude/Richter scale (ML ) defined by Charles Francis Richter in 1935, it uses a logarithmic scale; small earthquakes have approximately the same magnitudes on both scales. Despite the difference, news media often use the term "Richter scale" when referring to the moment magnitude scale.

2013

Ten people are killed in a bomb attack on a convoy carrying food supplies to a United Nations compound in Garowe in the Somali region of Puntland.
