first half of the 17th century, Javanese culture expanded, much of Western and East Java region are being Javanized. Mataram's campaign on Eastern Javanese principalities such as Surabaya and Pasuruan expanded Mataraman influences on Java. Mataram expansion includes Sundanese principalities of Priangan highlands; from Galuh Ciamis, Sumedang, Bandung and Cianjur. It was during this period that Sundanese people were exposed and assimilated further into Javanese Kejawen culture. Wayang Golek are Sundanese taking on Javanese Wayang Kulit culture, similar shared culture such as gamelan and batik also flourished. It is probably during this times that Sundanese language began to adopt the stratified degree of term and vocabulary to denote politeness, as reflected in Javanese language. In addition, Javanese scripts also used to write Sundanese as cacarakan. In political aspect, the incessant war of succession, treason, rebellion and court intrigue of Javanese Mataram during the last period of its history, has made Mataram being remembered in quite unflattering way. Combined with Javanese behaviour, such as obsession with elegance and refinements (Javanese: alus), subtleness, politeness, courtesy, indirectness, emotional restraint and consciousness to one's social stature, has made Mataram politics quite complicated, intricate and deceitful. As the result the negative aspects of Javanisation of contemporary Indonesian politics, such as dishonesty, deceptive, treacherousness, rigidity of social hierarchy, authoritarianism and arbitrariness, accompanied by fondness of status display and arrogance, is often attributed to and called as "Mataramization". A typical negative description of priyayi behaving like the member of Javanese upper class. Catur Sagotra Catur Sagotra means four entities that still have a single root kinship, referring to the royal families who succeeded the Islamic Mataram dynasty. These kingdoms are Kasunanan Surakarta, Kasultanan Yogyakarta, Kadipaten Mangkunagaran, and Kadipaten Pakualaman. The formation of Catur Sagotra began in 2004. King of Surakarta Sri Susuhunan Paku Buwono XII (before he died) once gave the mandate to Mrs. Nani Soedarsono to continue the noble ideals of Catur Sagotra. Catur Sagotra is a joint idea of the four Javanese kings at that time, namely Sri Susuhunan Paku Buwono XII, Sri Sultan Hamengku Buwono IX, Sri Paku Alam VIII and Sri Mangku Nagoro VIII. The purpose of Catur Sagotra is to unite the four breeds in the bonds of the same cultural philosophy and historical linkages of Mataram's ancestors.
