Problem: The city is governed pursuant to the Home Rule Charter of the City of Detroit. The city government is run by a mayor and a nine-member city council and clerk elected on an at-large nonpartisan ballot. Since voters approved the city's charter in 1974, Detroit has had a "strong mayoral" system, with the mayor approving departmental appointments. The council approves budgets but the mayor is not obligated to adhere to any earmarking. City ordinances and substantially large contracts must be approved by the council. The Detroit City Code is the codification of Detroit's local ordinances.

Problem: The interwar period was also marked by a radical change in the international order, away from the balance of power that had dominated preWorld War I Europe.

The League was undermined by the bellicosity of Nazi Germany, Imperial Japan, the Soviet Union, and Mussolini's Italy, and by the non-participation of the United States, leading many to question its effectiveness and legitimacy.
