History

Although regular races between professional watermen had been known since 1715 when Doggett's Coat and Badge was instituted, amateur racing was unknown before 1808. Meanwhile, recreational rowing had begun in Oxford very much earlier, with students rowing in single wherries at least as early as 1769.

The first amateur races between organised clubs which prepared and trained for the event began in Oxford in 1815. In this year, crews from Brasenose College and Jesus College raced for the Head of the River, from Iffley Lock to Mr King's Barge, which was moored near the current Head of the River hotel. The event is also notable for the fact that both crews rowed in eight oared boats, specially built for the purpose. Such recreational as occurred at this time was usually conducted in pairs, or four or six oared cutters. The fact the racing was conducted in eight oared boats gave rise to the event being known as Eights.

Brasenose College and Jesus College recontested the event in 1816, with Brasenose again triumphing. Christ Church joined in the event from 1817, when they went Head, a position they retained until 1819. Christ Church did not row in 1820. The next recorded races, between Brasenose and Jesus, were in 1821 and 1822. A dispute about professional watermen being allowed in college crews precluded racing in 1823. Until this time, Jesus and Brasenose had each used paid coaches who rowed in the stroke seats of the crews.

From 1824, Christ Church and Exeter College began racing, with Exeter going Head in that year. A rule banning the use of "out college men" (i.e. men from other colleges) rowing in college crews saw the entry of Worcester College in 1825, University and Balliol Colleges in 1827, and Oriel and Trinity Colleges in 1828.

Head of the River – Men

Summer Eights has been held since 1815.

No racing occurred during World War I. In World War II, though college rowing continued, there were insufficient students for normal racing between colleges to be maintained. As a consequence, most colleges competed in composite clubs, and the number of crews competing was greatly curtailed. After the war, normal racing continued, and in 1946 college crews started in the order in which they finished in 1939.
