Ramnicu Sarat was the scene of battles between the Moldavians and the Walachians in 1434 and 1573, and between the Walachians and Turks in 1634.
The states beyond the Balkan now began to dread the advance of the Turks; at the instigation of the pope an allied army of 60,000 Serbs, Hungarians, Walachians and Moldavians attacked Lala Shahin.
Here Lazarus, king of Servia, had collected an army of roo,000 Serbs, Hungarians, Moldavians, Walachians and others.
The exiled princes took refuge with the Kizil Ahmedli, ruler of Kastamuni, who persuaded the Walachians to rebel against the Turks.
In 1442 Hunyadi drove the Turks from Hermannstadt and, at the head of an army of Hungarians, Poles, Servians, Walachians and German crusaders, succeeded in the ensuing year in expelling them from Semendria, penetrating as far as the Balkans, where he inflicted heavy losses on the Turkish general.
At the beginning of the 19th century it was but a poor village, and in 1812 when it was acquired by Russia from Moldavia it had only 7000 inhabitants; twenty years later its population numbered 35,000, while in 1862 it had with its suburbs 92,000 inhabitants, and in 1900 125,787, composed of the most varied nationalities - Moldavians, Walachians, Russians, Jews (43%), Bulgarians, Tatars, Germans and Gypsies.
The Walachians resisted desperately, elected Radu, a kinsman of Neagoe, voivode, and succeeded with Hungarian help in defeating Mahmud Bey at Grumatz in 1522.
The conflict was prolonged with varying fortunes until in 1524 the dogged opposition of the Walachians triumphed in the sultan's recognition of Radu.
The mechanical skill of the Walachians was found useful by the Turks, who employed them as carpenters and pontonniers; and during the siege of Vienna in 1683 the Walachian contingent, which, under the voivode erban Cantacu zene, had been forced to co-operate with the Turks, was entrusted with the construction of the two bridges over the Danube above and below Vienna.
The Walachians imitated every kind of Turkish and European manufacture; and, though the boiars imported finer glass from Venice and Bohemia, a glass manufactory had been established near Tirgovishtea which produced a better quality than the Polish.
Verantius of Sebenico, an eye-witness of the state of Moldavia at the beginning of the 16th century, mentions three towns of the interior provided with stone walls - Suciava, Chotim (Khotin) and Ncamtzu; the people were barbarous, but more warlike than the Walachians and more tenacious of their national costume, punishing with death any who adopted the Turkish.
The stipulations of the treaty, though deficient in precision (the Walachians, for instance, had no authentic record of the privileges enjoyed under Mahomet IV.), formed the basis of future liberties in both principalities; but for the moment all reforms were postponed.
