What was the purpose of Liberty Bonds during World War I?

Liberty Bonds were specifically issued by the U.S. government during World War I as a means to raise funds to support military operations and the war effort. These bonds were sold to American citizens as a way to encourage public investment in the war, allowing individuals to lend money to the government with the promise of being repaid with interest after a certain period. The sale of Liberty Bonds helped to finance the costs associated with sending troops abroad, supplying equipment, and supporting allies. The campaign to promote these bonds also instilled a sense of patriotism among the populace, further motivating citizens to contribute financially to the war effort. Thus, the primary purpose of Liberty Bonds was to gather the necessary financial resources to sustain the United States' involvement in World War I.
