read the preamble
we the people of the united states, in order to form a more perfect union, establish justice, insure domestic tranquility, provide for the common defence, promote the general welfare, and secure the blessings of liberty to ourselves and our posterity, do ordain and establish this constitution for the united states of america
the preamble states that the constitution was established to \form a more perfect union.\ which historical action most directly expanded democratic participation in the united states?

• the dred scott v sandford decision (1857), which ruled that african americans could not be u.s. citizens, denying them legal rights and access to political participation.
• the 15th amendment (1870), which granted african american men the right to vote and prohibited racial discrimination in elections, expanding democratic participation.
• the alien and sedition acts (1798), which restricted the freedoms of speech and press, limiting citizens ability to criticize the government and engage in political debate.
• the three-fifths compromise (1787), which limited representation by counting enslaved individuals as three-fifths of a person in congressional apportionment

Explanation:

To solve this, we analyze each option:

1. Dred Scott v. Sandford (1857): This decision denied African Americans U.S. citizenship and political rights, reducing democratic participation.
2. 15th Amendment (1870): It granted African American men the right to vote and prohibited racial discrimination in elections, expanding democratic participation.
3. Alien and Sedition Acts (1798): Restricted speech/press, limiting citizens’ ability to engage in politics, reducing participation.
4. Three - Fifths Compromise (1787): Limited representation by counting enslaved people as 3/5 of a person, reducing democratic participation (especially for enslaved individuals and their communities).

So the action that expanded democratic participation is the 15th Amendment.

• Analyzed each option's impact on democratic participation. Dred Scott and Alien/Sedition Acts, Three - Fifths Compromise reduced participation. 15th Amendment granted voting rights to African American men, expanding it.

Answer:

The 15th Amendment (1870), which granted African American men the right to vote and prohibited racial discrimination in elections, expanding democratic participation.
