TFW your country says you can't become President of Nicaragua so you become President of your country.
William Walker was an adventurer, mercenary, filibuster, politician, and the 20th President of the United States from 1881 to 1884. After invading Mexico with a private army in 1853, he had set up his own personal Republic and placed it under the laws of the State of Louisiana, legalizing slavery. Later, he had declared himself President of Lower California and Sonora before being forced out of the country by the Mexican Army. At his trial, he was acquitted for all crimes and soon set out for another expedition to Nicaragua. During his time there, he had set up another English-speaking Republic supported by American businesses and legalized slavery again during his tenure.
However, he would be overthrown by the conservative Legitimist party and the British navy, forcing him to flee to Louisiana in 1963, which was under the control of the Confederate States of America. After the city of New Orleans was captured, he later decided to renounce his loyalty to the Confederacy, joining the Union Army as a soldier. In reward for his bravery on the battlefield, he would be granted his own personal company of men by General Benjamin Button to wage guerilla warfare against Confederate troops. As the Civil War came to a close, Walker decided to enter politics as both a supporter of state's rights and manifest destiny, while also renouncing his support of slavery.
During the 1880 elections, Walker entered as a Presidential candidate and won the nomination, thanks to his reputation as a war veteran, a patriot, and a true American hero. With Grover Cleveland as his running mate, he managed to defeat the unpopular incumbent Rutherford B. Hayes in a landslide victory. During his Presidency, began to rebuild the U.S Navy, firmly implemented the gold standard, and fought against high tariffs during his first years in office. Later, he would refuse to grant voting rights to African-Americans and oversaw the disbanding of the Freedmen's Bureau led by General Oliver Otis Howard.
Later, President Walker would invade the Diaz regime in Mexico to expand America's southern borders and to build new settlements for African-Americans across the country. Eventually, he would declare war on Britain as well following the Venezuela crisis of 1883. However, most historians believe that the war was an act of revenge for his betrayal by British admiral Nowell Salmon in Nicaragua. This would lead to the Panic of 1884 where the stock market crashed, prompting the uprising of African, Native, Mormon, socialist, and anarchist militias all over the nation. Following the Invasion of Superior, Walker ordered the Federal Electoral Commission to delay the 1884 election, enacting a wartime government. This prompted General Oliver Otis Howard to overthrow the President in the Salvation Coup, ending his Presidency and life in 1884.
