Lol @ Biimaal being slaves.
Biimaal sultanate owned slaves, sold slaves and controlled lower Shabelle from the 17th century when they defeated their rivals the Geledi sultanate until they clashed with the Italians colonialists who challenged their hegemony in Lower Shabeelle and eastern parts of Middle and Lower Jubba.
Marka
The town, which was founded by Arab or Persian traders, was in existence by the 10th century. The first Somalis to settle near there arrived in the 13th century, and in the 17th century the town, its hinterland, and caravan routes from the interior were controlled by the Bimal, a subgroup of one of the four major Somali clans, who traded extensively in ivory, slaves, cattle, and hides.
Hadiya is a southern Cushitic group whose Kingdom once ruled parts of central and southern Ethiopia. Many of the Habesha kings married from the Hadiya to establish strong ties with this powerful Kingdom.
The first clear written reference to any Galla or Somali group is found in
the writings of the thirteenth-century Arab geographer, Ibn Sa’id. Ibn
Sa’id says that Merca, a town on the southern Somali coast near the Shebeli
River, was the ‘capital of the Hawiye country’, which consisted of more
than fifty villages (or districts or tribes)
This area is today the home of the
Hawiye Somali clan-family, so there is good reason to assume that the Merca
region has been occupied continuously by the same Somali group for the
past 700 years. In fact, we can probably extend this to 800 years, for the
geographer al-Idrisi remarks that Merca was the region of the ‘Hadiye’
in the twelfth century. It is quite likely that the extant texts contain an
error, and that it should be ‘Hawiye’, as Guillain, Schleicher, and Cerulli
Merca; the ancient capital of the Hawiyya country.

The Hadiye of Ethiopia have no connection with Marka.
In Arabic the letters د و are very similar so when al Idrisi referred to Marka as "capital of الهدية" it was clear he was referring to Hawiye clan which are present in the town and meant to write الهوية.
Infact all confusion was cleared up when another explorer, Ibn Sa'iid, referred to Marka as "capital of the HAWIYE country" in the 13th century (one century after Al Idrisi).
Now let's look at the Ajuuraan (Hawiye) Empire that ruled the area throughout the Middle Ages.
Hawiye founded Marka and it has always been a Hawiye city.
Biyomaal only recently came from Ethiopia.
