The name Bea has its origins in the Latin language and derives from the word "beatus," which means "blessed" or "happy." It was a popular name during the Middle Ages in various European countries, particularly in Italy and Spain.

In the 12th century, the Italian form of the name, Beatrice, gained widespread popularity due to the famous poet Dante Alighieri's muse, Beatrice Portinari. Dante's epic poem, "The Divine Comedy," immortalized Beatrice as a symbol of divine love and spiritual enlightenment.

The shortened version, Bea, emerged as a diminutive form of Beatrice and became a distinct name in its own right. Its usage can be traced back to the 13th century in various regions across Europe.

One of the earliest recorded individuals with the name Bea was Bea of Laon, a 13th-century French noblewoman and writer. She is known for her work "Le Roman de Silence," a narrative poem that explores gender roles and identity.

In the 16th century, Bea was the name of a Spanish mystic and nun, Blessed Beatriz de Silva, who founded the Order of the Immaculate Conception. She was beatified by the Catholic Church in 1976.
