After her marriage to Diego Rivera in 1929, she went to New York with him but found herself homesick and lonely once again. Shortly after, in 1939, they divorced and Kahlo moved back to Mexico. Their divorce did not last long, however, and they remarried in 1940 after only a year of being apart. It was during this separation that she started developing her art and became a well-established artist in her own right. Over the next few years, her art was displayed in galleries around the world. But eventually, she could not attend the openings because of the pain in her leg and she was bedridden in a body cast because of her fragile back. Kahlo died in her sleep when she was forty-seven years old. A few years later, her Blue House (her childhood home) became the Frida Kahlo Museum and thirty years after that, the Mexican government declared Kahlo’s work a national treasure.
