At the beginning of the period the Time of Troubles disorganized the frontier defenses and led to much destruction. The Oka region was raided almost every year, but with decreasing frequency. 1633 may have been the last crossing of the Oka. We hear more frequently of raids at such places as Kursk and Voronezh, implying stronger defense in the north and a southern movement of the Russian population. The Belgorod Line of forts was begun about 1633 and seems to have had noticeable effects after about 1640. We hear of raids on Poland in 1614-21, 1624-28, 1633, 1640 and 1642.
Answer this question: How many years since the first and last raid passed that we heard about in Poland?

I början av perioden disorganiserade tiden för problem gränsförsvaret och ledde till stor förstörelse. Okaregionen plundrades nästan varje år, men med minskande frekvens. 1633 kan ha varit den sista korsningen av Oka. Vi hör oftare talas om räder på sådana platser som Kursk och Voronezj, vilket antyder ett starkare försvar i norr och en sydlig rörelse av den ryska befolkningen. Belgorodlinjen av fort påbörjades omkring 1633 och tycks ha haft märkbara effekter efter omkring 1640. Vi hör talas om räder mot Polen åren 1614-21, 1624-28, 1633, 1640 och 1642. Svara på denna fråga: Hur många år sedan den första och sista räden passerade som vi hörde talas om i Polen?
