Sunderland AFC was founded in 1879, initially as Sunderland and District Teachers' Association Football Club, a team formed by local schoolteachers; a year later membership was opened to non-teachers and the club adopted its current name. Sunderland quickly became one of the leading forces in English football — in the 1890s, under first manager Tom Watson, the club won three championships in four seasons, prompting Football League founder William McGregor to dub the side the "Team of All Talents". In total, Sunderland won six national championships – in 1892, 1893, 1895, 1902, 1913 and 1936 – and spent a then-record 68 consecutive seasons in the top division, right up until 1958.
Among the club's historic feats is a record 9-1 victory over fierce rivals Newcastle United at St James' Park in 1908, still the biggest margin of victory in the history of the derby fixture. The 1935/36 title-winning side featured the prolific strike partnership of Raich Carter and Bobby Gurney, who between them scored 62 of the team's 109 league goals that season.
The club also won the FA Cup twice, in 1937 and again in 1973, when a Second Division Sunderland side beat Leeds United, one of the strongest clubs of the era, in a result still regarded as one of the greatest upsets in the competition's history.
The nickname The Black Cats did not accompany the club from the very beginning – it was only officially adopted in 2000, following a fan vote, although the black cat motif had appeared in the club's symbolism since the early 20th century. Earlier, during the club's time at Roker Park, supporters and players were known as the "Rokerites".
After years of decline and fluctuation between divisions – including back-to-back relegations in 2017 and 2018 that took the club as low as League One – Sunderland made a dramatic return to the Premier League in May 2025, winning promotion through the play-offs under head coach Régis Le Bris, a moment supporters on Wearside compared to some of the finest in the club's history.
The club's current home is the Stadium of Light, opened in 1997 on the site of the former Monkwearmouth Colliery. The ground's name, like the Davy lamp memorial standing outside it, references the region's mining past. The club's red-and-white colours have for generations remained a significant part of the identity of a city where football has long held a special place in local culture.
