Francis "Frank" Hague, born in Jersey City, was the fourth of eight children to John D. and Margaret Hague (nee Fagen), immigrants from County Cavan, Ireland. He was raised in Jersey City's Second ward, an area known as The Horseshoe due to its shape which wrapped around a railroad loop. The ward was created when the Republican-controlled legislature gerrymandered a district within Jersey City in 1871 to concentrate and isolate Democratic, and mostly Catholic, votes. By age 14, Hague was expelled from school prior to completing the sixth grade for poor attendance and unacceptable behavior.

Technically, Hague's only responsibility as mayor was to appoint the school board. Otherwise, he was merely first among equals, with no powers over and above the other four commissioners. However, soon after taking office, he wrested control of the Hudson County Democratic Party from Wittpenn. This allowed him to significantly influence the makeup of the commission in this overwhelmingly Democratic city. He soon built the organization into one of the most powerful political machines in the country. Hague himself became very wealthy, owning a $125,000 summer home in Deal, living in a large apartment in the best building in the city, and able to give a $50,000 altar to a local Catholic church. He also had the support of a significant faction of Republicans which dated to his initial election as mayor, when he cut a deal with then-Governor Walter Edge in which Edge effectively ceded North Jersey to Hague in return for keeping South Jersey for himself. Also, as public safety commissioner (a post he held throughout his entire tenure), he controlled the two departments with the most patronage appointments in the city. This post also placed responsibility for maintaining public order in his hands. Hague soon extended his influence statewide by helping to elect his "puppets" as governor. In the 1919 gubernatorial election, Hague endorsed State Senator Edward I. Edwards and aggressively campaigned for him. Edwards carried Hudson County by 50,000 votes, which was enough for him to win statewide by just under 15,000 votes. Hague proclaimed himself leader of the New Jersey Democratic Party, and Edwards allowed him to recommend dozens of appointments to high state offices. Democrats won five out of eight gubernatorial races between 1919 and 1940, more often than not due to massive landslides in Hudson County. However, he was never able to extend his dominance to the state legislature. Hague was able to stay in power despite a nearly constant effort to turn him out of office from 1921 onward. He was also able to avoid prosecution despite numerous federal and state investigations in part due to the fact he took most of his kickbacks in cash. However, from the early 1940s onward, many of the older ethnic groups started moving to the suburbs. They were replaced by Poles, Italians, Eastern Europeans and African-Americans. Hague never adapted his methods to the new groups. Hague had little tolerance for those who dared oppose him publicly. He relied on two ordinances of dubious constitutionality to muzzle critics. A 1920 ordinance effectively required people making political speeches to obtain clearance from the chief of police. A 1930 ordinance gave the public safety commissioner--Hague himself--the power to turn down permits for meetings if he felt it necessary to prevent "riots, disturbances or disorderly assemblage." The latter ordinance was struck down as unconstitutional by the Supreme Court of the United States, but continued to be enforced for several years after that decision. The police were also allowed to stop and search anyone without probable cause or a warrant after 9 pm.
