Strato I

Strato I Dikaios (Greek: Στράτων Δίκαιος Strátо̄n Díkaios, “Strato the Just”) also known as Stratha in Sanskrit, was a Yavana King (reigned 125/120-110 BCE), the son and successor of Menander, Strato’s mother, Agathoclea ruled as Queen Mother and regnant for Strato until 120 BCE, when he was of age to succeed his father. He was dynastically succeeded by his son, Menander II.

Date and genealogy
Until recently, consensus was that he ruled between c. 130–110 BCE in Northern India and that his father was the great king Menander I. Menander ruled the entire Indo-Greek empire, but in this scenario, the western parts including Paropamisade and Arachosia gained independence after the death of Menander I, pushing Strato and Agathokleia eastwards to Gandhara and Punjab. This view was introduced by Tarn and defended as recently as 1998 by Bopearachchi.

The modern view, embraced by R. C. Senior and probably more solid since it is founded on numismatical analyses, suggests that Strato I was a later king, perhaps ruling from 110–85 BCE, though perhaps still a descendant of Agathokleia. In this case, Agathokleia was the widow of another king, possibly Nicias or Theophilus.

A third hypothesis was presented in 2007 by J. Jakobsson: according to this, the coins of Strato in fact belong to two kings who both may have ruled around 105–80 BCE, though in different territories: This theory was based on difference in titles, in monograms and coin types between the two.
 * Strato Soter and Dikaios (Greek: ΣΤΡΑΤΩΝ Ο ΣΩΤΗΡ ΚΑΙ ΔΙΚΑΙΟΣ "Strato the saviour and just/righteous"), was Agathokleia's son.
 * Strato Epiphanes Soter (Greek: ΣΤΡΑΤΩΝ Ο ΕΠΙΦΑΝΗΣ ΣΩΤΗΡ "Strato the illustrious, saviour"), was a middle-aged king who may have been Agathokleia's brother and ruled in western Punjab.

Events during his reign
Agathocleia's importance was gradually downplayed on the coins, so presumably her guardianship ended when Strato came of age. Strato I was also the only Indo-Greek king to appear bearded, probably to indicate that he was no longer an infant. Strato I, or the two Stratos, fought for hegemony in Punjab with the king Heliokles II, who overstruck several of their coins. There were very likely wars with other kings as well. The middle-aged Strato, according to the third theory, was succeeded by his son Polyxenios, who ruled only for a short time. A hoard of Strato's coins was found in Mathura outside New Delhi, which may have been the easternmost outpost of the Indo-Greek territory.

Coins
The coins of Strato show portraits aging from a youth to middle-aged. They have been divided into the following periods, where period 8 may belong to the second king.
