Customs war of 1431

After signing a ceasefire agreement with her brother Osman Yazi of Osmany, effectively ending the Dissolution War, the Sultana of Arana, Mustafaya Yazi, is now trying to win by coin what she could not win by sword. The pretender Aledin sits in Mersin with an iron tight grib on Karaman Bay, allowing him to impose tolls and virtually control transportation up and down the southern parts of the Chorenese Coast.
First, she forced the city of Tytos to introduce a right of stable, blocking imported merchandise to prevent being flooded by cheap goods coming from Ayyub manufactories, whose large scale production they cannot compete with.
She also obligated foreign traders to sell their wares in Tytos where local traders would have the right to redistribute it. Many saw this as a cleverly disguised attack on Sidaran trade. Aledin Suleiman of Sidaris retaliated with an absolute ban of Aranid wares in Ezurum and Boyazi. That was a great blow for Aranid merchants, so Mustafaya increased the tax on Sidaran products. Customs officers of both countries are on high alert as the conflict continues.
