The Supreme Court’s upcoming ruling on President Barack Obama’s health care overhaul law comes after a century of debate over what role the government should play in helping people in the United States afford medical care. A look at the issue through the years:

1912: Former President Theodore Roosevelt champions national health insurance as he unsuccessfully tries to ride his progressive Bull Moose Party back to the White House.

1929: Baylor Hospital in Texas originates group health insurance. Dallas teachers pay 50 cents a month to cover up to 21 days of hospital care per year.

1935: President Franklin D. Roosevelt favors creating national health insurance amid the Great Depression but decides to push for Social Security first.
