With same-sex marriage now legal in all parts of the UK, it can sometime be easy to forget how different attitudes to homosexuality were in the past, and how much change has taken place over the past 50 years.
For hundreds of years gay people have struggled to be accepted and treated the same as people who are not gay.
In fact it wasn't until 1967, that two men were able to be in a relationship together without the fear of being arrested.
LGBT+ stands for lesbian, gay, bisexual and transgender. The + is an inclusive symbol to mean 'and others' to include people of all identities.

Turing was a mathematician who cracked something called the Enigma code, which is thought to have shortened the war by several years.
He was also a victim of mid-20th Century attitudes to homosexuality and in 1952 was arrested because being homosexual was illegal in Britain at this time.
In 2013 he was pardoned for this 'crime', and in 2017 the government agreed to officially pardon men accused of 'crimes' like this, meaning they will no longer have a criminal record.
This pardoning has come to be known as the Alan Turing law.
In 2019 Turing was named the most "iconic" figure of the 20th Century and his face now appears on the £50 note.

Marsha P. Johnson was an African American transgender-rights activist, whose work in the 1960s and 1970s had a huge impact on the LGBT+ community.
At this time, being gay was classified as a mental illness in the United States. Gay people were regularly threatened and beaten by police, and were shunned by many in society.
In June 1969, when Marsha was 23 years old, police raided a gay bar in New York called The Stonewall Inn. The police forced over 200 people out of the bar and onto the streets, and then used excessive violence against them.
Marsha, who was living and working in New York at the time, was one of the key figures who stood up to the police during the raids.
Marsha resisted arrest, but in the following days, led a series of protests and riots demanding rights for gay people.
News of these protests spread around the world, inspiring others to join protests and rights groups to fight for equality.

In 1964 Allan Horsfall and a group of friends set up the North West Homosexual Law Reform Committee, even giving out his home address as the base for the organisation. To be so open at that time was very brave.
It became the first campaigning organisation outside of London set up and run by gay men, and its work directly led to homosexuality no longer being illegal.
Later the North West Committee was transformed into the Campaign for Homosexual Equality (CHE), which was the largest LGBT organisation there has ever been in the UK, with more than 5,000 members and 120 local groups all over the country when it was at its biggest.

He was asked to join the government's committee looking into homosexual offences which led to the Wolfenden Report, which recommended that having a homosexual relationship should no longer be a criminal offence.
This laid the foundations for a later law which partially decriminalised male homosexuality for the first time in England and Wales.
Goronwy was described as the "most perceptive member of the committee", and the one who successfully argued that the committee should take evidence directly from homosexual men.

Edie decided to sue and said that the law was discriminating against same-sex couples.
She did and was successful. Her fight led to an Act called the Defence of Marriage Act being overturned.
