The codification of sociology as a word, concept, and popular terminology is identified with Emmanuel Joseph Sieyès (see 18th century section) and succeeding figures from that point onward. It is important to be mindful of presentism, of introducing ideas of the present into the past, around sociology. Below, we see figures that developed strong methods and critiques that reflect on what we know sociology to be today that situates them as important figures in knowledge development around sociology. However, the term of "sociology" did not exist in this period, requiring careful language to incorporate these earlier efforts into the wider history of sociology. A more apt term to use might be proto-sociology that outlines that the rough ingredients of sociology were present, but had no defined shape or label to understand them as sociology as we concepualize it today.
The sociological reasoning may be traced back at least as far as the ancient Greeks, whose characteristic trends in sociological thought can be traced back to their social environment. Given the rarity of extensive or highly-centralized political organization within states, the tribal spirit of localism and provincialism was in open season for deliberations on social phenomena, which would thus pervade much of Greek thought.

Proto-sociological observations can be seen in the founding texts of Western philosophy (e.g. Herodotus, Thucydides, Plato, Polybius, etc.). Similarly, the methodological survey can trace its origins back to the Domesday Book ordered by King of England, William the Conqueror, in 1086.
Sociological perspectives can also be found among non-European thought of figures such as Confucius.

In the 13th century, Ma Duanlin, a Chinese historian, first recognized patterns of social dynamics as an underlying component of historical development in his seminal encyclopedia, Wénxiàn Tōngkǎo (文献通考; 'General Study of Literary Remains').
There is evidence of early Muslim sociology from the 14th century. In particular, some consider Islamic scholar Ibn Khaldun, a 14th-century Arab from Tunisia, to have been the first sociologist and, thus, the father of sociology. His Muqaddimah (later translated as Prolegomena in Latin), serving as an introduction to a seven-volume analysis of universal history, would perhaps be the first work to advance social-scientific reasoning and social philosophy in formulating theories of social cohesion and social conflict.

Concerning the discipline of sociology, Khaldun conceived a dynamic theory of history that involved conceptualizations of social conflict and social change. He developed the dichotomy of sedentary life versus nomadic life, as well as the concept of generation, and the inevitable loss of power that occurs when desert warriors conquer a city. Following his Syrian contemporary, Sati' al-Husri, the Muqaddimah may be read as a sociological work; six books of general sociology, to be specific. Topics dealt with in this work include politics, urban life, economics, and knowledge.

The work is based around Khaldun's central concept of asabiyyah, meaning "social cohesion", "group solidarity", or "tribalism". Khaldun suggests such cohesion arises spontaneously amongst tribes and other small kinship groups…

The term "sociologie" was first coined by the French essayist Emmanuel Joseph Sieyès (1773–1799), derived the Latin socius, 'companion'; joined with the suffix -ology, 'the study of', itself from the Greek lógos (λόγος, 'knowledge').

Formal institutionalization of sociology as an academic discipline began when Emile Durkheim founded the first French department of sociology at the University of Bordeaux in 1895. In 1896, he established the journal L'Année Sociologique.

A course entitled "sociology" was taught for the first time in the United States in 1875 by William Graham Sumner, drawing upon the thought of Comte and Herbert Spencer rather than the work of Durkheim. In 1890, the oldest continuing sociology course in the United States began at the University of Kansas, lectured by Frank Blackmar. The Department of History and Sociology at the University of Kansas was established in 1891 and the first full-fledged independent university department of sociology was established in 1892 at the University of Chicago by Albion W. Small (1854–1926), who in 1895 founded the American Journal of Sociology. American sociology arose on a broadly independent trajectory to European sociology. George Herbert Mead and Charles H. Cooley were influential in the development of symbolic interactionism and social psychology at the University of Chicago, while Lester Ward emphasized the central importance of the scientific method with the publication of Dynamic Sociology in 1883.

The first sociology department in the United Kingdom was founded at the London School of Economics in 1904. In 1919 a sociology department was established in Germany at the Ludwig Maximilian University of Munich by Max Weber, who had established a new antipositivist sociology. The "Institute for Social Research" at the University of Frankfurt (later to become the "Frankfurt School" of critical theory) was founded in 1923.[29] Critical theory would take on something of a life of its own after WW2, influencing literary theory and the "Birmingham School" of cultural studies.

The University of Frankfurt's advances along with the close proximity to the research institute for sociology made Germany a powerful force in leading sociology at that time. In 1918, Frankfurt received the funding to create sociology's first department chair. The Germany's groundbreaking work influenced its government to add the position of Minister of Culture to advance the country as a whole. The remarkable collection of men who were contributing to the sociology department at Frankfurt were soon getting worldwide attention and began being referred to as the "Frankfurt school." Here they studied new perspectives on Marx' theories, and went into depth in the works of Weber and Freud. Most of these men would soon be forced out of Germany by the Nazis, moving to America. In the United States they had a significant influence on social research. This forced relocation of sociologists enabled sociology in America to rise up to the standards of E…
