Has been described as a surrealist or magical realist, Frida Kahlo celebrity heights was a Mexican painter known for her many portraits, self-portraits, and works inspired by the nature and artifacts of Mexico. Inspired by the country's popular culture, she employed a naïve folk art style to explore questions of identity, postcolonialism, gender, class, and race in Mexican society. Her paintings often had strong autobiographical elements and mixed realism with fantasy. She is also known for painting about her experience of chronic pain.

Born to a German father and a mestiza mother, Kahlo spent most of her childhood and adult life at La Casa Azul, her family home in Coyoacán. Although she was disabled by polio as a child, Kahlo had been a promising student headed for medical school until being injured in a bus accident at the age of 18, which caused her lifelong pain and medical problems. During her recovery, she returned to her childhood interest in art with the idea of becoming an artist.

Kahlo's interests in politics and art led her to join the Mexican Communist Party in 1927, through which she met fellow Mexican artist Diego Rivera. The couple married in 1929 and spent the late 1920s and early 1930s travelling in Mexico and the United States together. During this time, she developed her artistic style, drawing her main inspiration from Mexican folk culture, and painted mostly small self-portraits that mixed elements from pre-Columbian and Catholic beliefs. Her paintings raised the interest of surrealist artist André Breton, who arranged for Kahlo's first solo exhibition at the Julien Levy Gallery in New York in 1938; the exhibition was a success and was followed by another in Paris in 1939. While the French exhibition was less successful, the Louvre purchased a painting from Kahlo, The Frame, making her the first Mexican artist to be featured in their collection. Throughout the 1940s, Kahlo participated in exhibitions in Mexico and the United States and worked as an art teacher. She taught at the Escuela Nacional de Pintura, Escultura y Grabado ("La Esmeralda") and was a founding member of the Seminario de Cultura Mexicana.

Kahlo's work as an artist remained relatively unknown until the late 1970s, when her work was rediscovered by art historians and political activists. By the early 1990s, not only had she become a recognized figure in art history, but she was also regarded as an icon for Chicanos, the feminism movement, and the LGBTQ+ community. Kahlo's work has been celebrated internationally as emblematic of Mexican national and Indigenous traditions and by feminists for what is seen as its uncompromising depiction of the female experience and form.

Estimates vary on how many paintings Kahlo made during her life, with figures ranging from fewer than 150 to around 200. Her earliest paintings, which she made in the mid-1920s, show influence from Renaissance masters and European avant-garde artists such as Amedeo Modigliani. Towards the end of the decade, Kahlo derived more inspiration from Mexican folk art, drawn to its elements of "fantasy, naivety, and fascination with violence and death". The style she developed mixed reality with surrealistic elements and often depicted pain and death.

Similarly to many other contemporary Mexican artists, Kahlo was heavily influenced by Mexicanidad, a romantic nationalism that had developed in the aftermath of the revolution. The Mexicanidad movement claimed to resist the "mindset of cultural inferiority" created by colonialism, and placed special importance on Indigenous cultures.

Kahlo's paintings often feature root imagery, with roots growing out of her body to tie her to the ground. This reflects in a positive sense the theme of personal growth; in a negative sense of being trapped in a particular place, time and situation; and in an ambiguous sense of how memories of the past influence the present for good and/or ill. In Kahlo's paintings, trees serve as symbols of hope, of strength and of a continuity that transcends generations. Kahlo often featured her own body in her paintings, presenting it in varying states and disguises: as wounded, broken, as a child, or clothed in different outfits, such as the Tehuana costume, a man's suit, or a European dress. She used her body as a metaphor to explore questions on societal roles. Her paintings often depicted the female body in an unconventional manner, such as during miscarriages, and childbirth or cross-dressing.

Kahlo's reputation as an artist developed late in her life and grew even further posthumously, she gradually gained more recognition in the late 1970s when feminist scholars began to question the exclusion of female and non-Western artists from the art historical canon and the Chicano Movement lifted her as one of their icons.
