The Somerset Coal Canal was built in the early 19th century to reduce the cost of transportation of coal and other heavy produce. The first 16 kilometres (10 mi), running from a junction with the Kennet and Avon Canal, along the Cam valley, to a terminal basin at Paulton, were in use by 1805, together with several tramways. A planned 11.7 km (7.3 mi) branch to Midford was never built, but in 1815 a tramway was laid along its towing path. In 1871 the tramway was purchased by the Somerset and Dorset Joint Railway (S&DJR), and operated until the 1950s.

On 8 February 1963, a military coup in Iraq led by a Ba'athist–Nasserist alliance toppled Qasim, who was subsequently shot dead. Abdel Salam Aref, a Nasserist, was chosen to be the new president. A similar alliance toppled the Syrian government on 8 March. On 14 March, the new Iraqi and Syrian governments sent Nasser delegations to push for a new Arab union. At the meeting, Nasser lambasted the Ba'athists for "facilitating" Syria's split from the UAR, and asserted that he was the "leader of the Arabs". A transitional unity agreement stipulating a federal system was signed by the parties on 17 April and the new union was set to be established in May 1965. However, the agreement fell apart weeks later when Syria's Ba'athists purged Nasser's supporters from the officers corps. A failed counter-coup by a Nasserist colonel followed, after which Nasser condemned the Ba'athists as "fascists".
How did Nasser describe the Ba'athists?
