Buried ancestors are memorialized as 'Guardian" spirit of the khunt or genealogical family symbolized by burial stone sasandiri (not to be confused with sasangdiri, which means turmeric (crushing) stone). These are placed flat on the ground, but do not mark "graves" as such. Rather, bones of the deceased, who are cremated or buried immediately after death, are placed under the sasandiri, where previous ancestors' bones are also present. They are usually put in an earthen pot and kept there from the time of the cremation or burial till the time of the jangtopa ceremony when the actual placing of bones in the sasandiri can take place. Once every year, all members of the family are required to visit burial stones to pay their respects. This practice is formally forbidden by the Church for Christianized Munda tribals, although in reality Christians infrequently are present during the rituals. There are other stones for ancestors as well, e.g., the memorial stones (bhodiri, headstones), which are placed in an erect position, usually closer to the homestead. The landscape of chotanagpur is dotted with clusters of these two types of stones, sasandiri (burial stones) and bhodiri (head-stones).
Since ancient times the Munda people spread through all surrounding areas, including the chotanagpur region. In early times group having same surname or killi (who sought their lineage from a single ancestor), settled in an area-specific fashion. Each killi is identified with a specific region, though now in general the people are free to settle where they wish, and have settled all over Jharkhand
Endogamous marriage is normal with the exception of marriage to members of the Santhal, Ho, Kharia and Oraon (Kurukh) communities. However, the current population is better educated and members sometimes abandon Munda tradition to marry a non tribal. Harsh punishments such as 'Jaat nikala'(Caste Banishment) may be pronounced by community chieftains in such cases. Marriage is forbidden between persons belonging to the same Gotr. A marriage between a bride and bridegroom of the same gotr is considered incest, and such a relation is socially undesirable.Gotr means Blood relation,same surname,same village gotr relation is like relation of brother and sister.
The Santhal, Ho and Kharia communities are considered blood-brother tribals, marriage with them is common. However, marriage with an Oraon is acceptable only due to a special relationship, the "Uncle-Nephew" relation. The reasons for this relationship are surrounded by many myths and remain lost in antiquity.
Mostly Munda people follow the Sarna religion, believing in a God called Singbonga.
However one-fourth of them have adopted Christianity.Among Christian Mundas, there are Roman Catholic Mundas and Protestant Mundas, the latter having several denominations.

After independence the name of the party was changed to the Jharkhand Party, to accommodate non-tribals seeking to achieve long term goals. He was the first to demand a separate Jharkhand state for tribals. He captained the Indian field hockey team to clinch the gold in the 1928 Summer Olympics in Amsterdam.

Government started collecting taxes by force and warrant was issued to arrest Nirmal Munda. Nirmal Munda took it as challenge, gave a simultaneous call to the people to gather at Simko (a village near Raiboga Police station, Orissa) on 25 April 1934. Captain Boscoe, a political agent, arrived with armed forces and asked people to identify Nirmal Munda. Having failing to get any response, the agent gave firing order which resulted in loss of some 300 people lives. Nirmal Munda was arrested.'Simko Firing'was an historic movement in India's freedom of struggle in general and of sundargarh district in particular
Jesuit Father John-Baptist Hoffmann (1857–1928) spent his life studying the language, customs, religion and life of the Mundas. He published the first Munda grammar in 1903. Later (with the help of Menas Orea, a Munda wise man and scholar to whom he paid rich tribute) Hoffmann brought out a Encyclopaedia mundarica, 15 volumes, gathering all that was then known of the Munda people. The first edition was published posthumously in 1937. A third edition came to press in 1976.
