may be Mount Kenya, where the Galana River originates. Thus, Malindi has existed as a Swahili settlement since at least the 13th century. Once rivalled only by Mombasa for dominance in this part of East Africa, Malindi has traditionally been a port city. In 1414, the town was visited by the fleet of the Chinese explorer Zheng He. Malindi's ruler sent a personal envoy with a giraffe as a present to China on that fleet. The Portuguese explorer Vasco da Gama met Malindi authorities in 1498 to sign a trade agreement and hire a guide for the voyage to India, when he erected a coral pillar. Vasco da Gama was given a warm reception from the Shiek of Malindi, which contrasted with the hostile reception he encountered in Mombasa. The pillar stands to this day, though there have been calls by conservationists to take care of it, since soil erosion might make the pillar fall into the ocean. It is a fairly popular tourist attraction for both local and international tourists. In 1498 Malindi was a prosperous town with a population between 5,000 and 10,000. The majority of the population was Muslim by this period, having converted largely between the 13th and 14th centuries. Like other Medieval Swahili towns, the ruling class or wazee was made up of the heads of the wealthiest patrician families. Similar to other Bantu-speaking peoples, these clan leaders elected a mwenye mui or chief who spoke on behalf of the patricians. The Portuguese mistakenly titled these individuals "Kings," misunderstanding the nature of Swahili political organization. The wazee spoke both Swahili and Arabic, and claimed mythological origins from the East, most often Persia. Malindi's main source of prosperity was the export of ivory and rhino horns as well as exporting agricultural products such as coconuts, oranges, millet and rice. In the years before the arrival of the Portuguese, Malindi was a regional power but lagged significantly behind the two greatest states, Mombasa and Kilwa. When, in 1499, the Portuguese established a trading post in Malindi that served as a rest stop on the way to and from India, they were eagerly welcomed by the wazee who sought to use the Portuguese military might to establish themselves over their rivals in Mombasa. In 1500, King Dom Manuel I offered vassal status to Malindi. Malindi supported Portugal's successful efforts to conquer Kilwa and Mombasa in 1505. In 1509
