Ukrainian Cossacks in the context of "Wild Fields"

China proper, also called Inner China or Han China, are terms used primarily in the Western world in reference to the traditional "core" regions of Chinese civilization centered around the Yellow River and Yangtze River valleys. There is no fixed definition for China proper as many administrative, cultural and territorial shifts have occurred throughout history. One definition refers to the original heartland regions of the Chinese civilization, the Central Plain (southern North China Plain around the lower Yellow River valley) as well as the historical Nine Provinces; another to the Eighteen Provinces inside Shanhai Pass designated by the Qing regime. In contrast, Outer China is a term usually includes the peripheral marchland regions such as Gobi Desert,, Tarim Basin, Northeast China, Dzungaria, Tibetan Plateau and Yungui Plateau, which were historically autonomous regions with unstable allegiance to the authority of Chinese monarchs.

The term was first used by the Europeans during the 17th century to distinguish the historical "Han lands" (Chinese: 漢地, i.e. regions long dominated by the majority Han Chinese population) from "frontier" regions of China where Han populations intermix with other indigenous ethnicities (e.g. Turkic peoples such as Uyghurs, Kazakhs and Uzbeks, Mongolic peoples, and Tibeto-Burmese peoples such as Tibetans, Yi and Bai) and newer foreign immigrants (e.g. Slavic colonists such as Russians and Ukrainian Cossacks), sometimes known as "Outer China". There was no direct translation for "China proper" in the Chinese language at the time due to differences in terminology used by the Qing regime to refer to the regions.

The Ukrainian National Revival (Ukrainian: Українське національне відродження, romanized: Ukrainske natsionalne vidrodzhennia) took place during a period when the territory of modern Ukraine was divided between the Austrian Empire, the Kingdom of Hungary, and the Russian Empire after the partitions of Poland at the end of the 18th century. The period took place soon after the Haidamaka Uprisings (also known as Koliivshchyna) rocked lands of the former Cossack Hetmanate.

The movement arose at a time when the Ukrainian national resistance was almost entirely subjugated and largely driven underground. All state institutions under the Cossack Hetmanate were completely liquidated along with the Cossack movement. The European territory of the Russian Empire had successfully crossed the Dnieper and extended towards Central Europe, as well as reaching the shores of Black Sea.

The Batoh (Batih) massacre (Polish: Rzeź polskich jeńców pod Batohem) was a mass execution of Polish captives after the Battle of Batih on 3–4 June 1652 near Ladyzhyn (now in Ukraine). It was carried out by Ukrainian Cossacks under the command of Hetman Bohdan Khmelnytsky.

Initially the captured Polish soldiers belonged to the Cossacks' allies, the Crimean Tatars. After the battle, the Cossacks paid the Tatars for possession of the prisoners, and promptly slaughtered the Polish captives to avenge Khmelnytsky's defeat at Berestechko in June 1651. According to Jasienica, it was the Cossack colonels Ivan Zolotaryenko and Ivan Vysochin who bought them from the Tatars. According to Widacka, Cossack's commander Khmelnytsky himself contributed 50,000 thalers for that purpose. According to Hrushevsky and Pasicznyk, Duda, and Sikora, the decision to execute the prisoners was made by Khmelnytsky himself. Afterward, between 3,000 and 5,000 and 8,000 Polish soldiers were tied up and massacred in two days of methodical beheadings and disembowelments. Zolotaryenko supervised the executions yelling "Revenge for Berestechko!", a reference to an earlier Cossack defeat at the hands of the Poles in the Battle of Berestechko.

The Trilogy (1884–1888) is a series of three novels written by the Polish author Henryk Sienkiewicz. The series follows dramatized versions of famous events in Polish history, weaving fact and fiction. It is considered a great literary work, on par with Adam Mickiewicz's Pan Tadeusz.

The first novel, titled With Fire and Sword, chronicles the mid-17th century Khmelnytsky Uprising, a revolt by the Ukrainian Cossacks in the Polish–Lithuanian Commonwealth.

The Intercession of the Theotokos, or the Protection of Our Most Holy Lady Theotokos and Ever-Virgin Mary, is a Christian feast of the Mother of God celebrated in the Eastern Orthodox and Byzantine Catholic Churches on October 14 (Julian calendar: October 1).The feast celebrates the protection afforded the faithful through the intercessions of the Theotokos (lit. Mother of God, one Eastern title of the Virgin Mary).

The feast is commemorated in Eastern Orthodoxy as a whole, but by no means as fervently as it is in Russia, Belarus, and, especially, Ukraine. In the Slavic Orthodox Churches it is celebrated as the most important solemnity besides the Twelve Great Feasts and Pascha. In Ukraine, it has a special meaning through its connection to the spirituality of the Ukrainian Cossacks and, accordingly and more recently, to Defenders of Ukraine Day.
