President Barack Obama has been vocal in his opposition to Russian counterpart Vladimir Putin’s military intervention in Ukraine. Focus has shifted from the new government in Kiev, Ukraine’s capital, to Crimea, a region Russian troops seized control of Saturday.

Meanwhile, politicians and pundits are divided over what the United States’ role should be in the conflict. Washington Post columnist David Ignatius criticized Putin’s actions on Face the Nation, saying Ukraine "is not prepared to go backwards" to a Russian regime. He then offered up some context about Crimea’s history.

"Crimea became part of Ukraine only in 1954," he said. "Crimea was historically part of Russia, and (Nikita) Khrushchev gave it to Ukraine in a gesture that mystified some people."

Ignatius was correct in saying that Ukraine has only controlled the Crimean Peninsula since 1954 -- a claim we also heard from U.S. Rep. Mike Roger, R-Mich., on Fox News Sunday. Not up on your Soviet history? We’ll review the facts.

Crimea is an eastern Ukrainian peninsula located on the Black Sea. It’s connected to the rest of the country by a small strip of land. Out of its 2 million residents, about 60 percent identify as Russian. That’s the highest concentration of Russian speakers in Ukraine. Although the territory belongs to Ukraine, Russia stations part of its Black Sea fleet in Sevastopol as part of a pre-existing agreement between the two countries.

As Ignatius pointed out, Crimea hasn’t always been part of Ukraine. Here’s a quick rundown of what’s happened in the region since the Ottoman Empire used the peninsula as a hub for slave trade.

1783: Russia annexed Crimea.

1853 : The Crimean War began, lasting three years. Russia lost to an alliance of the Ottoman Empire, France, Britain and Sardinia. Crimea remained part of Russia.

1917 : Crimea briefly became a sovereign state before becoming a base for the White Army of anti-Bolshevik forces in the Russian War.

1921 : The peninsula, now called the Crimean Autonomous Soviet Socialist Republic, became part of the Soviet Union.

1942 : Nazi Germany took control of Crimea. Featured Fact-check Says Melania Trump is the “first FLOTUS to visit troops in a combat zone since 1969.”

1944 : Joesph Stalin forcibly deported all Muslim Tatars, a group of 300,000 who had lived on the peninsula for centuries, due to members’ alleged cooperation with Germany during World War II. Many returned to Crimea in the 1980s and 1990s.

1945 : After World War II, the autonomous Soviet republic was dissolved and Crimea became a province of the Soviet Union called the Crimean Oblast.

1954 : Russian Premier Nikita Khrushchev transferred the Crimean Oblast to Ukraine. It’s often reported that it was a gesture of goodwill from Khrushchev, who had Ukrainian roots.

1991 : The Soviet Union collapsed. Many expected President Boris Yeltsin, the new president of the Russian Federation, to take Crimea for Russia. But he didn’t bring it up during negotiations with Ukraine.

1997: Ukraine and Russia signed a treaty that allowed Russia to keep its fleet in Sevastopol. The agreement’s since been extended, so the fleet is set to remain there until at least 2042.

As for Ignatius’ claim that Khrushchev’s decision to give Crimea to Ukraine in 1954, we found literature to support that. Slate’s Joshua Keating offered up possible reasons for the land transfer, including the 300th anniversary of Ukraine’s merger with tsarist Russia and Khrushchev’s ties to Ukraine.

Though Khrushchev’s gesture had unclear motives, it didn’t seem like a problem for Russia at the time, only garnering a one-sentence write-up in the official Soviet newspaper. It became a bigger issue in the region once the Soviet Union collapsed decades later.

So the story of the Crimean Peninsula is long and complicated, to say the least. And there could be more news to come as war threatens Eastern Europe. Today, Crimea’s residents are divided on the issue of Russia’s military intervention. Generally speaking, ethnic Russians support Russia’s involvement in the region, while Tatars and Ukrainians express pro-Ukrainian sentiments.

Our ruling

Ignatius said Crimea belonged to Russia until 1954, when Khrushchev gave the land to Ukraine, then a Soviet republic. Ignatius’ history lesson explains why Russians remain so intertwined with Crimea and why some Americans are worried that Russians will try to annex the peninsula.

We rate Ignatius’ statement True.

Correction: About 60 percent of people living in Crimea identify themselves as Russian. An earlier version of this story described the statistic differently. This post was updated at 1 p.m. March 3, 2014.
