Kushan on Wekipedia.
The Kushan Empire originally formed in the early 1st century AD under Kujula Kadphises in the territories of ancient Bactria on either side of the middle course of the Oxus (or Amu Darya), and later based in eastern and central Afghanistan and the northwest of Indian Subcontinent.
During the 1st and early 2nd centuries AD the Kushans expanded rapidly across the northern part of the Indian Subcontinent at least as far as Saketa and Sarnath near Varanasi (Benares) where inscriptions have been found dated to the first few years of era of the most famous Kushan ruler, Kanishka which apparently began about 127 AD.

Former Kelaniya University historian’s in a Sinhala newspaper states that Kanishka [78-110 AD ] obtained control of the Great Northern Trade Routes between China and Rome by defeating the Chinese army. Due to this the Chinese and Roman Traders had easy access to both India and Sri lanka. During this period the Roman and Chinese mariners/traders exchanged goods in the free ports of Sri Lanka.
During this period Sri Lanka was ruled by King Wasaba[65-109 AD]. According to Prof Jayasena the Chinese Chronicles mentions a trade agreement between China and King Wasaba who was known as ” Rajadhiraja Devaputra. This was in 97 AD . Even Kanishka too was addressed as Devaputra in the Chinese Chronicles. According to Mr OMR Sirisena in “Kushana Golds in Sri Lanka”- Daily News May 28 1997 . Kushqan were the four grest powers of the world duirng the period along with Rome, Persia and China. Kanishka was a great patron of Buddhism and conducted the fourth great Buddhist Council. The Saka Era in our astrology as 78 AD is belived to be the date of accession of this King. Mr Sirisena an expert on Gold Coins of Sri Lanka describes that according to the Rasavahini an ancient text of the Island a group of Buddhist monks from Sri Lanka had had visited places of interest assciated with Buddha and visited Devaputra nagara , which is identified the Kushan Capital Purusapura.
Mr Sirisena states
” I had the rare opportunity to see a gold coin of Kushana dynasty which was found in the country lying between Okkampitiya and Maligawa, perhaps a flourishing region og ancient Ruhuna.. This was of Huvishka, the succssor of Kanishka. This coins ahs a Badfrian inscriptuion on the obverse written in Greek script Shahonanoshao Oohki Koshaano [ King of Kings Huvishka Kusana].
