Christine Louise of Oettingen-Oettingen was Duchess of Brunswick-Lüneburg. She was the maternal grandmother of Holy Roman Empress Maria Theresa, Emperor Peter II of Russia and also Charles I, Duke of Brunswick-Wolfenbüttel.

Peter II Alexeyevich was Emperor of Russia from 1727 until 1730, when he died at the age of 14. He was the only son of Tsarevich Alexei Petrovich and Charlotte Christine of Brunswick-Lüneburg. After Catherine I's death, Alexander Menshikov controlled Peter II, but was thwarted by his opponents and exiled by Peter. Peter was also influenced by favorites like Prince Aleksey Dolgorukov, leading to a neglect of state affairs and the tightening of serfdom. Peter's reign was marked by disengagement, disorder, and indulgence. He was engaged to Ekaterina Dolgorukova, but died suddenly of smallpox before the marriage, thus making him the last male agnatic member of the House of Romanov.
