A major objective of the first Ming expedition (1405–1407) was the kingdom of Kozhikode. Historians presume that the fleet stayed from December 1406 to April 1407 at Kozhikode. Ambassadors from Kozhikode, among envoys from other states, accompanied the returning (first expedition) fleet bringing articles of "tribute" to Nanking in 1407. On the second expedition, in 1408–09, Zheng He again visited Kozhikode—stopping as well in "Chochin" (Kochi). The envoys in the second expedition (1408–1409) carried out the formal "investiture" of the Samoothiri of Kozhikode "Mana Piehchialaman". A memorial inscription was erected in Kozhikode to commemorate the investiture. The Chinese titles and gifts (brocades and gauzes) were given to the Samoothiri and his retinue by the Chinese envoys. Presumably a stay of about four months was made at Kozhikode, possibly from December 1408 to April 1409. The third expedition (1409–1411) - the first one to sail to beyond India - also visited Kozhikode. The fleet sailed on from Kozhikode to Sri Lanka in 1411. The fourth (1413–1415), fifth (1417–1419), sixth (1421–22) and seventh (1431–33) fleets also visited Kozhikode. A number of tribute delegations – in 1421, 1423, and 1433, among others – were dispatched by the Kozhikode rulers to Nanking and Peking. Presents from Kozhikode included horses and black pepper. Brocades of several types were presented to the some of the Kozhikode envoys. Ma Huan visited Kozhikode several times, and describes the trade in the region. Fei-Hsin also notices the brisk trade at Kozhikode.
