Van Praag states that the Ming court established diplomatic delegations with Tibet merely to secure urgently needed horses. Wang and Nyima argue that these were not diplomatic delegations at all, that Tibetan areas were ruled by the Ming since Tibetan leaders were granted positions as Ming officials, that horses were collected from Tibet as a mandatory "corvee" tax, and therefore Tibetans were "undertaking domestic affairs, not foreign diplomacy". Sperling writes that the Ming simultaneously bought horses in the Kham region while fighting Tibetan tribes in Amdo and receiving Tibetan embassies in Nanjing. He also argues that the embassies of Tibetan lamas visiting the Ming court were for the most part efforts to promote commercial transactions between the lamas' large, wealthy entourage and Ming Chinese merchants and officials. Kolmas writes that while the Ming maintained a laissez-faire policy towards Tibet and limited the numbers of the Tibetan retinues, the Tibetans sought to maintain a tributary relationship with the Ming because imperial patronage provided them with wealth and power. Laird writes that Tibetans eagerly sought Ming court invitations since the gifts the Tibetans received for bringing tribute were much greater in value than the latter. As for the Yongle Emperor's gifts to his Tibetan and Nepalese vassals such as silver wares, Buddha relics, utensils for Buddhist temples and religious ceremonies, and gowns and robes for monks, Tsai writes "in his effort to draw neighboring states to the Ming orbit so that he could bask in glory, the Yongle Emperor was quite willing to pay a small price". The Information Office of the State Council of the PRC lists the Tibetan tribute items as oxen, horses, camels, sheep, fur products, medical herbs, Tibetan incenses, thangkas (painted scrolls), and handicrafts; while the Ming awarded Tibetan tribute-bearers an equal value of gold, silver, satin and brocade, bolts of cloth, grains, and tea leaves. Silk workshops during the Ming also catered specifically to the Tibetan market with silk clothes and furnishings featuring Tibetan Buddhist iconography.

Why does Van Praag believe the Ming court set up a diplomatic delegation with Tibet?
Answer: to secure urgently needed horses

Problem: Although the Founding Fathers of the United States did not originally intend for American politics to be partisan, early political controversies in the 1790s over the extent of federal government powers saw the emergence of two proto-political parties- the Federalist Party and the Democratic-Republican Party, which were championed by Framers Alexander Hamilton and James Madison, respectively. However, a consensus reached on these issues ended party politics in 1816 for a decade, a period commonly known as the Era of Good Feelings.
In which year did the period known as the "Era of Good Feelings" begin?
The answer is the following: 1816

After the Union of Horodo the Lithuanian nobility acquired equal status with the Polish szlachta, and over time began to become more and more polonized, although they did preserve their national consciousness, and in most cases recognition of their Lithuanian family roots. In the 16th century some of the Lithuanian nobility claimed that they were of Roman extraction, and the Lithuanian language was just a morphed Latin language. This led to paradox: Polish nobility claimed own ancestry from Sarmatian tribes, but Sarmatians were considered enemies to Romans. Thus new Roman-Sarmatian theory was created. Strong cultural ties with Polish nobility led that in the 16th century the new term to name Lithuanian nobility appeared slektaa direct loanword from Polish szlachta. From the view of historical truth Lithuanians also should use this term, slekta (szlachta), to name own nobility, but Lithuanian linguists forbade the usage of this Polish loanword. This refusal to use word szlachta (in Lithuanian text slekta) complicates all naming.
What did some lithuanian nobility claim that caused a paradox?
they were of Roman extraction
