Decisive defeat of the Filiki Eteria by the Ottomans at Drăgășani (in Wallachia).

Filiki Eteria or Society of Friends was a secret political and revolutionary organization founded in 1814 in Odessa, whose purpose was to overthrow Ottoman rule in Greece and establish an independent Greek State. Society members were mainly young Phanariot Greeks from Constantinople and the Russian Empire, local political and military leaders from the Greek mainland and islands, as well as several Orthodox Christian leaders from other nations that were under Hellenic influence, such as Karađorđe from Serbia, and Tudor Vladimirescu from Romania. One of its leaders was the prominent Phanariote Prince Alexander Ypsilantis. The Society initiated the Greek War of Independence in the spring of 1821.

Drăgășani is a city in Vâlcea County, Romania, near the right bank of the Olt river, and on the railway between Caracal and Râmnicu Vâlcea. The city is well known for the vineyards on the neighboring hills that produce some of the best Wallachian wines.

Wallachia or Walachia is a historical and geographical region of modern-day Romania. It is situated north of the Lower Danube and south of the Southern Carpathians. Wallachia was traditionally divided into two sections, Muntenia and Oltenia. Dobruja could sometimes be considered a third section due to its proximity and brief rule over it. Wallachia as a whole is sometimes referred to as Muntenia through identification with the larger of the two traditional sections.
