Pre-modern Ottoman armies used the horse-tail standard or
tugh rather than flags. Such standards remained in use alongside flags until the 19th century. A depiction of a tugh appears in the '''' by
Joseph Pitton de Tournefort (1718). War flags came into use by the 16th century. During the 16th and 17th centuries, Ottoman war flags often depicted the bifurcated
Zulfiqar sword, often misinterpreted in Western literature as showing a pair of
scissors. The
crescent symbol appears in flags attributed to
Tunis from as early as the 14th century (''''), long before Tunis fell under Ottoman rule in 1574. But the crescent as a symbol also had 14th-century associations with the Ottoman military and millennium-long associations with the city of Istanbul, which became the Ottoman capital after
its conquest in 1453. The Spanish Navy Museum in Madrid shows two Ottoman naval flags dated 1613; both are swallow-tailed, one green with a white crescent near the hoist, the other white with two red stripes near the edges of the flag and a red crescent near the hoist.
