John Tyler vs Sharif Ahmed

Upon William Henry Harrison's death, Tyler became the first vice president to assume the presidency. He insisted on being president, not acting president, setting the precedent for presidential succession.

Tyler vetoed two bills to reestablish a national bank, breaking with the Whig Party. His actions led to his expulsion from the Whig Party and the resignation of his entire cabinet except Secretary of State Daniel Webster.

Tyler approved the treaty negotiated by Secretary of State Daniel Webster with Britain, settling the northeastern boundary of the United States (Maine-New Brunswick). The treaty averted potential conflict with Britain.

Tyler signed a joint resolution for the annexation of Texas just before leaving office. The annexation added a large slaveholding territory to the U.S., leading to the Mexican-American War.

Tyler served as a delegate to the Virginia Secession Convention and voted for secession. He was elected to the Confederate House of Representatives but died before taking his seat.

As chairman of the Islamic Courts Union (ICU), Sharif Ahmed led the coalition that captured Mogadishu from US-backed warlords. The ICU established sharia law and brought temporary stability to the capital, but was later ousted by Ethiopian forces.

Sharif Ahmed was elected President of Somalia by the parliament in Djibouti as part of a UN-backed peace process. A former leader of the Islamic Courts Union, his election aimed to stabilize the country after years of civil war and Islamist insurgency.

Sharif Ahmed signed the Kampala Accord with the Speaker of Parliament, extending his term by one year in exchange for appointing a new prime minister. The deal was brokered by Uganda to resolve a political crisis, but was criticized by some as undemocratic.

Sharif Ahmed was defeated in the 2012 presidential election by Hassan Sheikh Mohamud. The election marked the end of the transitional government and the beginning of a new federal government, though Sharif remained a political figure.
