He was descended from Christian Dirkzoon Monderyan who lived in The Hague as early as 1670. The family moved to Winterswijk when his father, Pieter Cornelius Mondrian, was appointed head teacher at a local primary school. Mondrian was introduced to art from an early age. His father was a qualified drawing teacher, and, with his uncle, Fritz Mondrian (a pupil of Willem Maris of the Hague School of artists), the younger Piet often painted and drew along the river Gein. After a strict Protestant upbringing, in 1892, Mondrian entered the Academy for Fine Art in Amsterdam. He was already qualified as a teacher. He began his career as a teacher in primary education, but he also practiced painting. Most of his work from this period is naturalistic or Impressionistic, consisting largely of landscapes. These pastoral images of his native country depict windmills, fields, and rivers, initially in the Dutch Impressionist manner of the Hague School and then in a variety of styles and techniques that attest to his search for a personal style. These paintings are representational, and they illustrate the influence that various artistic movements had on Mondrian, including pointillism and the vivid colors of Fauvism. In 1893 he had his first exhibition. On display in the Gemeentemuseum Den Haag are a number of paintings from this period, including such Post-Impressionist works as The Red Mill and Trees in Moonrise. Another painting, Evening (Avond) (1908), depicting a tree in a field at dusk, even augurs future developments by using a palette consisting almost entirely of red, yellow, and blue. Although Avond is only limitedly abstract, it is the earliest Mondrian painting to emphasize primary colors. Mondrian's earliest paintings showing a degree of abstraction are a series of canvases from 1905 to 1908 that depict dim scenes of indistinct trees and houses reflected in still water. Although the result leads the viewer to begin focusing on the forms over the content, these paintings are still firmly rooted in nature, and it is only the knowledge of Mondrian's later achievements that leads one to search in these works for the roots of his future abstraction. Mondrian's art was intimately related to his spiritual and philosophical studies. In 1908, he became interested in the theosophical movement launched by Helena Petrovna Blavatsky in the late 19th century, and in 1909 he joined the Dutch branch of the Theosophical Society.
