'Trans', from 'transgender', was originally used to describe a person whose sense of personal identity and gender does not correspond to their sex at birth.

These days 'trans' is often used as an inclusive term for any or all non-conventional gender identities.

Historic England, the clever people who preserve Britain's heritage, hold a wonderful archive of references to trans people, history and activism.

"The interwar idea of ‘sex change’ implied that sex or gender fluidity was possible, and that individuals might choose their sex."

It was not until the 1950s that transitioning became possible in Britain. The great British trans pioneers were Michael Dillon (1915-1962) and Roberta Cowell (1918-2011).

April Ashley (1935-2021) campaigned to have her gender legally recognised. This was eventually made possible by the Gender Recognition Act 2004 and April was awarded an MBE for services to transgender equality at Buckingham Palace in 2012.

The series celebrates the labels that help people express their individuality and define their place in the world.
