Immediately below the mouth of the Mexcala, on
the border of the Pacific, were the lands of the Cuitlatecs,
and also the province or kingdom of Zacatollan,
whose capital was the modern Zacatula. Of these two
peoples absolutely nothing is known, save that they
were tributary to the Aztec empire, the latter having
been added to the domain of Tezcuco in the very last
years of the fifteenth century.
The provinces that extended south-westward from Anáhuac to the ocean, belonging chiefly to the modern state of Guerrero and included in what I have described as the Aztec empire proper, were those of the Tlahuicas, whose capital was Cuernavaca, the Cohuixcas, capital at Acapulco, the Yoppi on the coast south of Acapulco, and the province of Mazatlan farther inland or north-east. The name Tlapanecs is also rather indefinitely applied to the people of a portion of this territory in the south, including probably the Yoppi. Of the names mentioned we have met those of the Tlahuicas and Cohuixcas among the tribes newly springing into notice at the beginning of the Chichimec period. It is probable that nearly all were more or less closely allied in race and language to their Mexican masters, their political subjection to whom dates from about the middle of the fifteenth century.
MIZTECS AND ZAPOTECS.
The western slope of the cordillera still farther south-west, comprising in general terms the modern state of Oajaca, was ruled and to a great extent inhabited by the Miztecs and Zapotecs, two powerful nations distinct in tongue from the Aztecs and from each other. Western Oajaca, the home of the Miztecs, was divided into Upper and Lower Miztecapan, the latter toward the coast, and the former higher up in the mountains, and sometimes termed Cohuaixtlahuacan. The Zapotecs in eastern Oajaca, when first definitely known to history, had extended their power over nearly all the tribes of Tehuantepec, besides encroaching somewhat on the Miztec boundaries.
