"bring together," c.1600, from French rallier, from Old French ralier "reassemble, unite again," from re- "again" (see re-) + alier "unite" (see ally (v.)). Intransitive meaning "pull together hastily, recover order, revive, rouse" is from 1660s. Related: Rallied; rallying. Rally round the flag (1862) is a line from popular American Civil War song "Battle Cry of Freedom."
Rallying was again slow to get under way after a major war, but the 1950s were the Golden Age of the long-distance road rally. In Europe, the Monte Carlo Rally, the French and Austrian Alpines, and the Liège were joined by a host of new events that quickly established themselves as classics: the Lisbon Rally (Portugal, 1947), the Tulip Rally (the Netherlands, 1949), the Rally to the Midnight Sun (Sweden, 1951, now the Swedish Rally), the Rally of the 1000 Lakes (Finland, 1951 – now the Rally Finland), and the Acropolis Rally (Greece, 1956). The RAC Rally gained International status on its return in 1951, but for 10 years its emphasis on map-reading navigation and short manoevrability tests made it unpopular with foreign crews. The FIA created in 1953 a European Rally Championship (at first called the "Touring Championship") of eleven events; it was first won by Helmut Polensky of Germany. This was the premier international championship until 1973, when the FIA created the World Rally Championship for Manufacturers, won that first year by Alpine-Renault. Not until 1979 was there a World Rally Championship for Drivers, won that year by Björn Waldegård.
Most of the works drivers of the 1950s were amateurs, paid little or nothing, reimbursed their expenses and given bonuses for winning (although there were certainly exceptions, such as the Grand Prix drivers who were brought in for some events). Then in 1960 came arguably the first rallying superstar (and one of the first to be paid to rally full-time), Sweden's Erik Carlsson, driving for Saab.
