Although village's Latvian name has always been Iecava, internationally it was known by its German name Gross Eckau until the beginning of 20th century. It was the scene of a victory over Russian forces by Prussian troops fighting for Napoleon during his invasion of Russian Empire and was also the scene of fighting during the Second World War German retreat from the Soviet Union.
South of the city centre lies a park around the former Iecava Estate of the Graf Pahlen family. Only the foundation walls and some yard buildings remain. The French General Marshal MacDonald, who commanded the Prussian troops who were fighting as part of the Grand Armée, occupied the Gross-Eckau castle during the Napoleonic War with Russia.
Prominent Latvians born there include Friedrich Wilhelm Matisohn (1871-1913) and Arvīds Pelše (1899-1983).
In addition to farming, the town supports manufacturing enterprises including vegetable oil and white spirits.
