John Tyler (aka “His Accidency”) was the first Vice-President to inherit the Presidency. He was a longtime Democratic-Republican who was elected to the Vice Presidency on the Whig ticket, so he was rather unpopular with his former political supporters and had a tenuous relationship with his predecessor during his short vice-presidency.

Frederick William I (German: Friedrich Wilhelm I.; 14 August 1688 – 31 May 1740), known as the Soldier King (German: Soldatenkönig), was King in Prussia and Elector of Brandenburg from 1713 until his death in 1740, as well as Prince of Neuchâtel. Frederick William instituted major military reforms, and expanded the army to new limits. He also made efforts to reduce crime and corruption in his state and centralized his authority during his 27 years reign, cementing Prussia as a regional power. His other notable decisions would be the selling of Prussian overseas colonies and the foundation of the Canton system, as well as the conquest of the port of Stettin. He was succeeded by his son, Frederick the Great.
