Obrona ziem ruskich przed najazdami tatarskimi w latach 1575-1578

In the years 1575-1578 the Polish-Lithuanian Commonwealth used money to corrupt members of the court of the Sultan and Khan to protect the Ruthenian lands. On the one hand, the Poles “bought” their supporters from among the Crimean Tartars, and on the other hand, they wanted to influence the Khan using his sovereign, the Sultan. During this period, the Ruthenian nobility indeed defended their land against the Tartar invasions, but did not propose any changes to the system of defense. They did not see that their actions neither solved nor prevented the problem.
