The revolutionary leaders Pantelis Marinakis and Apostolis Limnios came from the village, and took part in the battles in Arcadia and Niokastro in 1824 and 1825 under Vasos Mavrovouniotis.

According to the communal archives from 1854, the village had 62 enlisted men that paid 989 piastres to avoid conscription.

The village was part of the municipality (koli) of Kontias and its inhabitantas sent a representative to the Lemnos provincial assembly.

It built an aqueduct and a fountain in 1922, donated for 200,000 drachmas by the brothers Nikolaos and Komninos Halamandaris.

It had 516 inhabitantas in 1928, among whom were many refugees from Minor Asia, employed mainly in the agriculture and animal husbandry.

In the Middle Ages, a village called Agiopavlitiko was situated on the site of present Poliochni.

In 1881 the place was mentioned as Polichni, which was changed into Poliochni after the discovery of ancient Poliochne near Kaminia.
