Artaxiad dynasty in the context of "Kingdom of Armenia (antiquity)"

Tigranes II, more commonly known as Tigranes the Great (Tigran Mets in Armenian; 140–55 BC), was a king of Armenia. A member of the Artaxiad dynasty, he ruled from 95 BC to 55 BC. Under his reign, the Armenian kingdom expanded beyond its traditional boundaries and reached its peak, allowing Tigranes to claim the title Great King or King of Kings. His empire for a short time was the most powerful state to the east of the Roman Republic.

Either the son or nephew of Artavasdes I, Tigranes was given as a hostage to Mithridates II of Parthia after Armenia came under Parthian suzerainty. After ascending to the Armenian throne, he rapidly expanded his kingdom by invading or annexing Roman and Parthian client-kingdoms. Tigran decided to ally with Mithridates VI of Pontus by marrying his daughter Cleopatra. At its height, Tigranes' empire stretched from the Pontic Alps to Mesopotamia and from the Caspian Sea to the Mediterranean. With captured vassals, his lands even reached the Red Sea and the Persian Gulf. Many of the inhabitants of conquered cities were forcibly relocated to his new capital, Tigranocerta. An admirer of the Greek culture, Tigranes invited many Greek rhetoricians and philosophers to his court, and his capital was noted for its Hellenistic architecture.

The Orontid dynasty, also known as the Eruandids or Eruandunis, ruled the Satrapy of Armenia until 330 BC and the Kingdom of Armenia from 321 BC to 200 BC. The Orontids ruled first as client kings or satraps of the Achaemenid Empire and after the collapse of the Achaemenid Empire established an independent kingdom. Later, a branch of the Orontids ruled as kings of Sophene and Commagene. They are the first of the three royal dynasties that successively ruled the ancient Kingdom of Armenia (321 BC–428 AD). Although the overthrow of Orontes IV and the accession of Artaxias I to the throne of Armenia in the early 2nd century BC is traditionally treated as the start of a new dynasty, Artaxias probably belonged to a branch of the Orontid dynasty. His descendants ruled Armenia until the 1st century AD.

The Arsacid dynasty, called the Arshakuni (Armenian: Արշակունի, romanized: Arshakuni) in Armenian, ruled the Kingdom of Armenia (with some interruptions) from 12 to 428 AD. The dynasty, a branch of the Arsacid dynasty of Parthia, reigned intermittently throughout the chaotic years following the fall of the Artaxiad dynasty until 62, when Tiridates I, brother of Parthian King Vologases I, secured Arsacid rule in Armenia as a client-king of the Roman Empire. However, he did not succeed in establishing his line on the throne, and various princes of different Arsacid lineages ruled until the accession of Vologases II, who succeeded in establishing his own line on the Armenian throne, which ruled the kingdom until the Sasanian Empire abolished it in 428.

Two of the most notable events in Armenian history during the Arsacid period were the conversion of Armenia to Christianity by Gregory the Illuminator and Tiridates III in the early 4th century; and the creation of the Armenian alphabet by Mesrop Mashtots c. 405. In contrast to the more Hellenic-influenced Artaxiads, Arsacid Armenia featured greater Iranian influence.

Artavasdes I (also spelled Artawazd/Artavazd) was the Artaxiad king of Armenia from approximately 160 BC to 115 BC. He was the son and successor of Artaxias I. Little is known about his reign. He is the subject of ancient Armenian folk traditions, which are recorded by later Armenian authors.

In c. 120 BC, the Parthian king Mithridates II (r. 124–91 BC) defeated Artavasdes I and made him acknowledge Parthian suzerainty. Artavasdes was forced to give the Parthians Tigranes (the future king Tigranes the Great) as a hostage, who was either his son or nephew.

Artaxias I (from Ancient Greek: Άρταξίας) was the founder of the Artaxiad dynasty of Armenia, ruling from 189 BC to 160 BC. Artaxias was a member of a branch of the Orontid dynasty, the earlier ruling dynasty of Armenia. He expanded his kingdom on all sides, consolidating the territory of Greater Armenia. He enacted a number of administrative reforms to order his expanded realm. He also founded a new capital in the central valley of the Araxes River called Artaxata (Artashat), which quickly grew into a major urban and commercial center. He was succeeded by his son Artavasdes I. Modern scholars regard him as the founder of independent Armenian statehood.

Artavasdes II (Ancient Greek: Ἀρταουάσδης Artaouásdēs), also known as Artavazd II, was king of Armenia from 55 BC to 34 BC. A member of the Artaxiad dynasty, he was the son and successor of Tigranes the Great (r. 95–55 BC), who ascended the throne of a still powerful and independent state. His mother was Cleopatra of Pontus, thus making his maternal grandfather the prominent King of Pontus Mithridates VI Eupator. Like his father, Artavasdes continued using the title of King of Kings, as seen from his coins.
