Hashtag United

Hashtag United Football Club was formed in March 2016 by Spencer Carmichael-Brown, a football YouTuber better known as Spencer FC or Spencer Owen. Carmichael-Brown had begun making YouTube videos in 2007 as a student at the University of Reading, and the team initially consisted of friends from school and university.

From their foundation, the team primarily played five, seven, and eleven-a-side exhibition matches, which were filmed and uploaded to their YouTube channel. By September 2016, the team's Instagram account had over 100,000 followers, their Twitter account 41,000, and a 'penalty challenge' video uploaded to YouTube had accumulated over two million views. Hashtag United played various teams including a Comedians XI whom they beat 19–1, Google, the GB Deaf Team, Barawa, and a Manchester City staff team, with opponents fielding former professional footballers such as Paul Dickov, Graeme Le Saux and Ray Parlour, and celebrities including Omid Djalili. At one point in 2016, the club was rumoured to be interested in signing professional footballer Adebayo Akinfenwa. In 2017, the club won the EE Wembley Cup, a competition that Carmichael-Brown had created in 2015. The team included Scott Pollock, winner of the Hashtag Academy competition in 2017, who went on to sign professional terms with Northampton Town.

In early 2018 Chelsea captain and Spanish international César Azpilicueta invested in the club and became a co-owner. Ahead of the 2018–19 season, the club joined the English football league system, initially being placed in Division One of the Spartan South Midlands League, before being moved to the Eastern Counties League after appealing that it was more suited to their Essex roots. After joining the pyramid, Carmichael-Brown stepped down as manager and was replaced by former East Thurrock United assistant manager Jay Devereux. Their first competitive match was a 3–2 away loss to Little Oakley on 4 August 2018. The club's first league season saw them reach the semi-finals of Division One Knock-Out Cup. They went on to win the Division One South title, earning promotion to the Essex Senior League. The 2019–20 season was abandoned due to the COVID-19 pandemic with the club second in the league, a point behind league leaders Saffron Walden Town and with three matches in hand. After the 2020–21 season was also curtailed due to the pandemic, at which point Hashtag United were top of the league, the club was promoted to the North Division of the Isthmian League based on the points per game accumulated over the two abandoned seasons. During their two seasons in the Essex Senior League, the club won 96 points from 38 games.

In 2022–23 Hashtag won 21 league matches in a row, going on to win the North Division title and earning promotion to the Isthmian League's Premier Division.
