When did the constitution give an all adult men the right to vote was it from the beginning before the civil law or after the civil law or during World War I?
The United States Constitution initially did not grant voting rights to all adult men.
According to the original Constitution adopted in 1787, voting rights were determined by the states and were generally restricted to white male property owners. Over time, however, the voting eligibility requirements began to change.
The first major milestone occurred with the ratification of the Fifteenth Amendment in 1870, following the Civil War. This amendment explicitly prohibited the denial or abridgment of the right to vote based on race, color, or previous condition of servitude. Though it aimed to guarantee voting rights to African American men, it was often undermined by discriminatory practices such as poll taxes and literacy tests.
The next significant development came during World War I, with the ratification of the Nineteenth Amendment in 1920. This amendment granted women the right to vote, marking a crucial step toward more inclusive suffrage.
Therefore, to answer your question, the Constitution did not grant all adult men the right to vote from the beginning. It began expanding suffrage with the Fifteenth Amendment after the Civil War and then extended voting rights to women with the Nineteenth Amendment during World War I.
