Vajrata was succeeded by his son Jajjuka, who had three sons Gogga,
Purnaraja and Devaraja. The three brothers built three temples of Vishnu on
the banks of Sarasvati at Prithudaka in the Kamal district. In the first half of
the 11th century the Tomaras came into conflict with the Muslim invaders.
With the rise of the Chahamanas of Sakambhari, they soon felt their
irresistible pressure. A Tomara chief named Rudrena, lost his life in a battle
with the Chahamana, Chandanaraja II. The struggle practically ended with
the capture of Delhi by the Chahamanas under Vigraharaja in the middle of
the 12th century.
Two-Stage Feudalism
Decentralised Nature of Early Medieval Polity The multiplicity of
regional powers and the absence of a unitary or paramount power have
obliged historians to suggest a shift in the nature of polity of the early middle
ages from 750 to 1200 AD. While traditional accounts of political history
emphasised the fluctuating relations between overlords and their vassals or
subordinates, Marxist scholars suggested a major structural change in polity
of the early medieval times. Early medieval polity is looked at as one of
decentralisation and disintegration, in sharp contrast to the early historical
polity which often encouraged forces of centripetality. The decentralised
nature of early medieval polity, according to Marxist historiography, is to be
appreciated, analysed and situated in the broader context of a new type of
formation in the early medieval period, viz., the emergence and
crystallisation of what is termed as Indian feudalism.
  First Stage—Feudalism from Above Marxists envisaged feudal
  formation in India in two stages: feudalism from above and feudalism
  from below. The first stage was the primary phase with direct relationship
  between a overlord and his tributary/autonomous vassals, without the
  prevalence of an intermediary land-owning class. The second stage was a
  more complex later phase witnessing          the rise of rural land-owners as
