Chronicon
         terrae Prussiae (Latin for "The Chronicle of the Prussian Land") is a chronicle of the Teutonic
         Knights, by Peter of Dusburg, finished in 1326. The manuscript is the first major chronicle of the Teutonic
         Order in Prussia and the Grand Duchy of Lithuania, completed some 100 years after the conquest of the crusaders into
         the Baltic region. It is a major source for information on the Order's battles with Old Prussians and Lithuanians. The chronicle
         is written in Latin and consists of four volumes. The first volume gives the background of the Order and its crusades in Outremer.
          The second volume narrates how the Order arrived to the Prussian land,  while the third volume details wars with Old Prussians
         and other Baltic tribes.  The fourth volume provides a historical context of other contemporary
          events in the world. The chronicle has an addendum of another 20  chapters dealing with events of 1326-1330, which may also
         have been  written by Peter of Dusburg.  The chronicle is based on local monastery annals, chronicles, reports  and narrations
         which Peter "considered reliable". Peter had access to  the Grand Masters' archive
         in Marienburg and witnessed some events himself. 
 
   
  
The chronicle contains some ethnographic data about the
         Old  Prussians, the indigenous people conquered by the Order. It provides  numerous chapters in the styles of religious visions,
         miracles, and hagiography,  aimed at the glorification of the mission of the Order. The war against  pagans is sacred and
         all knights who perish go to heaven. Peter takes  no interest in domestic policy of the Order; he does not describe  cities,
         trade, or colonization.  Rather the chronicle describes minor raids and clashes with great  detail. While narratives of events
         and battles are considered to be  reliable, ethnographic data is ideologically charged. As a priest Peter  tried to teach
         the reader. Pagan Prussians and Lithuanians are presented  as a moral example. They are pious in their own way, and Christians
          should be ashamed of their disobedient and sinful ways
