In 1596, it was named as a village, Balat, in the Ottoman nahiya (subdistrict) of Tibnin under the liwa' (district) of Safad, with a population of 56 households and 2 bachelors, all Muslim.

The villagers paid a fixed tax-rate of 25 % on agricultural products, such as wheat, barley, olive trees, vineyards, goats, beehives; in addition to occasional revenues, a press for olive oil or grape syrup and a water mill; a total of 6,000 akçe.

[1][2] In 1838, Eli Smith noted Blat's population as being Metawileh.

[3] On 27 December 1993, during the Israeli occupation of southern Lebanon, a Norwegian soldier was killed when an Israeli tank, stationed in neighbouring Aishiyeh, fired on his UNIFIL patrol outside Blat.

The Indian Army contingent with UNIFIL had a small base camp in the village.
