Albert Bierstadt was a German-American painter best known for his lavish, sweeping landscapes of the American West. He joined several journeys of the Westward Expansion to paint the scenes. He was not the first artist to record the sites, but he was the foremost painter of them for the remainder of the 19th century.

Bierstadt was born in Prussia, but his family moved to the United States when he was 1. He returned to study painting for several years in Düsseldorf. He became part of the second generation of the Hudson River School in New York, an informal group of like-minded painters who started painting along the Hudson River. Their style was based on carefully detailed paintings with romantic, almost glowing lighting, sometimes called luminism. Bierstadt was an important interpreter of the western landscape, and he is also grouped with the Rocky Mountain School.

Ferhat Abbas was an Algerian politician who acted in a provisional capacity as the then yet-to-become independent country's President from 1958 to 1961, as well as the first President of the National Assembly and the first acting President after independence. His political views evolved from pro-French collaboration to those of a revolutionary nationalist, over a period of approximately twenty years.

The Battle of Palo Alto was the first major battle of the Mexican–American War and was fought on May 8, 1846, on disputed ground five miles from the modern-day city of Brownsville, Texas. A force of some 3,700 Mexican troops – most of the Army of The North – led by General Mariano Arista engaged a force of approximately 2,300 United States troops – the Army of Occupation led by General Zachary Taylor.

On April 30, following the Thornton Affair, Mexican General Mariano Arista's troops began to cross the Rio Grande. On May 3, the troops began to besiege the American outpost at Fort Texas. Taylor marched his Army of Occupation south to relieve the siege. Arista, upon learning of his approach, diverted many of his units away from the siege to meet Taylor's force. The battle took place on May 8, three days before the formal declaration of war on Mexico by the United States. Arista ordered two cavalry charges, first against the American right flank and later against the left. Both were unsuccessful. The American victory is widely attributed to superior artillery, while the U.S. "light" artillery was much more mobile and accurate than that of the Mexican forces.
