What was the purpose of liberty bonds in the United states during world War 1?

Liberty bonds were issued by the United States government during World War I to finance military operations and support the war effort. By purchasing these bonds, citizens lent money to the government, which helped cover expenses related to the war, such as equipment and troop mobilization. In return, bondholders received interest over time, promoting a sense of patriotism and collective responsibility among Americans. The campaign to sell these bonds also aimed to engage the public in the war effort and bolster national unity.
