Constitution of Indiana

The Constitution of Indiana is the highest body of state law in the U.S. state of Indiana. It establishes the structure and function of the state and is based on the principles of federalism and Jacksonian democracy. Indiana's constitution is subordinate only to the U.S. Constitution and federal law. Prior to the enactment of Indiana's first state constitution and achievement of statehood in 1816, the Indiana Territory was governed by territorial law. The state's first constitution was created in 1816, after the U.S. Congress had agreed to grant statehood to the former Indiana Territory. The present-day document, which went into effect on November 1, 1851, is the state's second constitution. It supersedes Indiana's 1816 constitution and has had numerous amendments since its initial adoption.

Indiana's constitution is composed of a preamble, articles, and amendments. Among other provisions, it specifies a republican form of government (pursuant to Article IV, Section 4, of the U.S. Constitution) consisting of three branches: executive (including administration), legislative, and judicial. The state constitution also includes a bill of rights, grants suffrage and regulates elections, provides for a state militia, state educational institutions, and sets limits on government indebtedness. The Indiana General Assembly may amend the constitution, subject to ratification by vote of the people, as specified in Article 16 of Indiana's 1851 constitution.
