President Barack Obama has undoubtedly made a mark on American history.

Though Obama may be our first African-American president, he has also acted as a leader and uniting figure behind a number of progressive ideas and policies during his time in office.

From health care reform to international relations and beyond, take a look back at Obama’s most progressive accomplishments over the past eight years.

Love it or hate it, the Affordable Care
Love it or hate it, the Affordable Care Act (also known as Obamacare) will forever be linked with this president. Signed into law on March 23, 2010, the Affordable Care Act serves to protect Americans from unfair insurance practices and to make affordable health care coverage a reality for millions. The legislation has been both championed by Democrats and vilified by Republicans. While the Obama administration lauds the legislation as comprehensive health care reform that made coverage available to millions who did not previously have it, the GOP has slammed it as an unconstitutional mandate that hurts quality of care, among other issues.

Since President Obama urged action on raising the minimum wage in 2013, 18 states and Washington, D.C. have answered the call, according to the White House. Obama also supports the Raise the Wage Act, which was introduced in 2015 and would gradually raise the federal minimum wage to $12 per hour over the course of 11 years. So far, the bill has been read twice in the Senate and referred to the Committee on Health, Education, Labor, and Pensions, but has not progressed further.

In June 2012, President Obama announced an executive action that would allow undocumented immigrants who came to the United States before they were 16 years old to stay in the United States for as long as two years.

Those who do meet the guidelines could become eligible for employment authorization, according to U.S. Citizenship and Immigration Services. (Credit: AFP / Getty Images / Saul Loeb)
