The dialect spoken in Luri-i buzurg (Greater Lur) which is closely related to Persian. This dialect is spoken by the inhabitants of Bakhtiari, Kuh-Gilu-Boir Ahmed, in the north and east of Khuzistan, in the Mamasani district of Fars, and in some areas of Bushehr province.
The dialect spoken in Lur-i-Kuchek (Lesser Lor) which is closely related to southern Kurdish, with has some similarities to Persian. This dialect is spoken in Luristan, several districts of Hamadan (Malayer, Nahavand, Towisarkan) and by the inhabitants of south and southwest Ilam and northern part of Khuzistan province.
There is a 3rd group of Luri people that speak Luri Minjaee, they are ethnically part of Lur-e- kuchak but dialectically part of Lur-e-bozorg.
Lurs are a mixture of aboriginal Indo-Iranian tribes, originating from Central Asia. Michael M. Gunter states that they are closely related to the Kurds but that they "apparently began to be distinguished from the Kurds 1,000 years ago." He adds that the Sharafnama of Sharaf Khan Bidlisi "mentioned two Lur dynasties among the five Kurdish dynasties that had in the past enjoyed royalty or the highest form of sovereignty or independence." In the Mu'jam Al-Buldan of Yaqut al-Hamawi mention is made of the Lurs as a Kurdish tribe living in the mountains between Khuzestan and Isfahan. The term Kurd according to Richard Frye was used for all Iranian nomads (including the population of Luristan as well as tribes in Kuhistan and Baluchis in Kirman) for all nomads, whether they were linguistically connected to the Kurds or not.
Considering their NRY variation, the Lurs are distinguished from other Iranian groups by their relatively elevated frequency of Y-DNAHaplogroup R1b (specifically, of subclade R1b1a2a-L23). Together with its other clades, the R1 group, associated with Upper Palaeolithic West/CentralEurasia, comprises the single most common haplogroup among the Lurs.Haplogroup J2a (subclades J2a3a-M47, J2a3b-M67, J2a3h-M530, more specifically) is the second most commonly occurring patrilineage in the Lurs and is associated with the diffusion of agriculturalists from the Neolithic Near East c. 8000-4000 BCE. Another haplogroup reaching a frequency above 10% is that of G2a, with subclade G2a3b accounting for most of this. Also significant is haplogroup E1b1b1a1b, for which the Lurs display the highest frequency in Iran. Lineages Q1b1 and Q1a3 present at 6%, and T at 4%.
The authority of tribal elders remains a strong influence among the nomadic population. It is not as dominant among the settled urban population. As is true in Bakhtiari and Kurdish societies, Lur women have much greater freedom than women in other groups within the region.
The Lur peoples are diverse and individualistic in their religious views and practices. Religious views can differ immensely, even within a family group. While the overwhelming majority of Lurs are Shia Muslims, some practice an ancient Iranian religion known as Yaresan which has roots in Zoroastrianism, Mithraism and Manicheism. Traditionally the Lur people outwardly profess Shia Islam, but the degree of piety varies, and the religion of some is a mixture of Ahl-e Haqq involving a belief in successive incarnations combined with ancient rites.

Second Impression December 2003. pp 111: "Tribes always have been a feature of Persian history, but the sources are extremely scant in reference to them since they did not 'make' history. The general designation 'Kurd' is found in many Arabic sources, as well as in Pahlavi book on the deeds of Ardashir the first Sassanian ruler, for all nomads no matter whether they were linguistically connected to the Kurds of today or not. The population of Luristan, for example, was considered to be Kurdish, as were tribes in Kuhistan and Baluchis in Kirman"
