During the 18th century Tamm's inhabitants participated in the construction of the Duke of Württemberg's new residence in nearby Ludwigsburg, mostly as socagers. In these days, population skyrocketed, from 543 in 1741 to nearly 1000 in 1800. While Tamm was not directly affected by the Napoleonic Wars, it still suffered from the economic strain put on the entire region. Shortly after the war, in 1816, a famine hit, marking a temporary decline in Tamm's development. During the rest of the 19th century, the village grew steadily, getting connected to the railroad in 1877.
