Second Seminole War: American general Zachary Taylor leads 1,100 troops against the Seminoles at the Battle of Lake Okeechobee.

The Second Seminole War, also known as the Florida War, was a conflict from 1835 to 1842 in Florida between the United States and groups of people collectively known as Seminoles, consisting of Creek and Black Seminoles as well as other allied tribes. It was part of a series of conflicts called the Seminole Wars. The Second Seminole War, often referred to as the Seminole War, is regarded as "the longest and most costly of the Indian conflicts of the United States". After the Treaty of Payne's Landing in 1832 that called for the Seminoles' removal from Florida, tensions rose until fierce hostilities occurred in Dade's massacre in 1835. This engagement officially started the war although there were a series of incidents leading up to the Dade battle. The Seminoles and the U.S. forces engaged in mostly small engagements for more than six years. By 1842, only a few hundred native peoples remained in Florida. Although no peace treaty was ever signed, the war was declared over on August 14, 1842, by Colonel William Jenkins Worth.

Zachary Taylor was an American military officer and politician who was the 12th president of the United States, serving from 1849 until his death in 1850. Taylor was a career officer in the United States Army, rising to the rank of major general and becoming a national hero for his victories in the Mexican–American War. As a result, he won election to the White House despite his vague political beliefs. His top priority as president was to preserve the Union. He died 16 months into his term from a stomach disease. Taylor had the third-shortest presidential term in U.S. history and was the third president, after William Henry Harrison and James K. Polk, whose death has been traced to poor sanitation in Washington, D.C.
