The 15th, 19th, and 26th Amendments all granted what important right?

The 15th, 19th, and 26th Amendments to the United States Constitution are all significant in that they specifically address and expand the right to vote. The 15th Amendment, ratified in 1870, prohibits the federal and state governments from denying a citizen the right to vote based on "race, color, or previous condition of servitude," ensuring that African American men could exercise their voting rights. The 19th Amendment, ratified in 1920, granted women the right to vote, marking a pivotal moment in the women's suffrage movement. Finally, the 26th Amendment, ratified in 1971, lowered the voting age to 18, thus enfranchising younger citizens and acknowledging their right to participate in the democratic process. Collectively, these amendments underscore the evolution of voting rights in the United States, emphasizing the importance of inclusivity in the electoral system as society progressed toward greater equality.
