The king could promulgate new laws, raise taxes, or call for a levee en masse (pospolite ruszenie) only with the consent of the sejmiks, and the nobility were protected from judicial abuses.

These privileges were demanded by the szlachta as a compensation for their participation in the Thirteen Years' War.

Context and question: Regardless of the ability of the Luftwaffe to win air superiority, Adolf Hitler was frustrated that it was not happening quickly enough. With no sign of the RAF weakening, and Luftwaffe air fleets (Luftflotten) taking punishing losses, the OKL was keen for a change in strategy. To reduce losses further, a change in strategy was also favoured to take place at night, to give the bombers greater protection under cover of darkness.[b] On 4 September 1940, in a long address at the Sportspalast, Hitler declared: "And should the Royal Air Force drop two thousand, or three thousand [kilograms ...] then we will now drop [...] 300,000, 400,000, yes one million kilograms in a single night. And should they declare they will greatly increase their attacks on our cities, then we will erase their cities."
What kind of strategy did the Luftwaffe use to give their bombers better protection?
Answer: cover of darkness
