The history of Cambodia began in the first century A.D with the establishment of a State called Funan. Funan is still renowned as being the oldest Indianised State in the whole of Southeast Asia. Modern day Khmer customs and language evolved from this period in time. Sanskrit, which is part of the Mon Khmer family dialect, was the written and spoken language of that time. The officially known religion began with Hinduism, which over the years evolved into Buddhism. Distinct characteristics of that period still remain today. These features can be recognized in ancient buildings, and ancient farming methods, as well as country clothing.

The State of Funan was situated in what is known today as the southern province of and lasted for a period of 600 years. This dynasty gave way to the powerful Angkor Empire that was eventually responsible for establishing the Khmer Kingdom, as we know it today.

The following generation of powerful kings that belonged to the Angkorian dynasty are believed to have come from India and Javanese part of today's Indonesia. The dynasty reigned for a period of 650 years, and their empire covered much of South East Asia, as we know it today. Their territory stretched from Burma, which lies east, to the South China Sea and further north, right up to Laos.

Khmer kings, during this golden period of rule, built the most ornate and extensive temples or prasats known to mankind. These spectacular constructions were built throughout the kingdom, Angkor Wat, is of course the most famous. Amongst the most successful of the Angkorean kings was Preah Bat Jaya Varman II, Preah Bat Indra Varman I, Preah Bat Surya VarmanII, and Preah Bat Jaya Varman VII. Besides building the most majestic prasats on earth, they were also responsible for huge agricultural feats of engineering which included sophisticated irrigation systems, great water reservoirs, and countless canal systems that guaranteed food transport. Some of these systems are still in use even today.

Angkor became the capital of a great kingdom and the centre for government, education, religion, and commerce. However, in the late 13th century a sudden shift of power took place. Angkor was invaded and eventually, completely ravaged. Mankind’s most predominant creation on earth was plunged into total destruction. The entire population and wealth of a once proud civilization was abandoned and covered by tropical forest.

Following the abandonment of Angkor, Cambodia's capital population migrated south to Long Vek, then further to Ou Dong, and eventually to Phnom Penh. The destruction of the mighty Angkorian capital also caused a decline, adaptation, and eventual replacement of Hinduism. Theravada Buddhism became the national

Cambodia, a country in Southeast Asia in the southern part of Indochina, covers an area of 181,035 square kilometers and has a population of 13,124764 million (2003 est.). The country's shape is an almost-square polygon, with Kampong Thom Province as its central point. The country extends 440 kilometers from north to south and 560 kilometers from west to east. This shape makes Cambodia easy for tourists to navigate and poses no difficulties for the development of tourism. Among the 10 member countries of the Association of Southeast Asian Nations (ASEAN), Cambodia ranks eight in land size and seventh in population. Its geographical location makes Cambodia an easily accessible ecotourism destination for travelers in neighboring countries and other parts of the world.

The country is situated geographically between the 10th and 15th parallels north latitude and the 102th and 108th parallels east latitude.
The borders of Cambodia encompass 2,600 kilometers of which five-sizes are land and one-sixth is costal border.

The Kingdom of Cambodia is bounded on the northeast by the people's Democratic Republic of Laos, on the east and southeast by the Socialist Republic of Vietnam, and on the west and northwest by the Kingdom of Thailand.
The coastal boundary of Cambodia is 440 kilometers with medium depth tropical sea, rich in aquatic creatures that are good for aquatic business. In addition, there are beautiful, uninhabited islands, virgin beaches, white sand and fresh air, which are also good for tourism.
 

The country has a tropical climate-warm and humid. In the monsoon season, abundant rain allows for the cultivation of a wide variety of crops. This year-round tropical climate makes Cambodia ideal for developing tourism. Travelers need not fear natural disasters such as erupting volcanoes or earthquakes, and the country is not directly affected by tropical storms. Cambodia lies in a tropical zone between 10 and 14 degree of latitude north the equator. The temperature is fairly uniform throughout the year and averages 25 degree centigrade (77 degree Fahrenheit). The relative humidity is higher at night and usually in excess of 90 percent, during the day the average humidity is 80 percent.

Cambodia can be visited throughout the year. However those planning to travel extensively by road should avoid the last two months of the rainy season when some countryside roads may be impassable.

The climate distinguished by four major seasons. The most pleasant is the cool-dry season from November to February during which temperatures are cooler (average 20-28 degree Celsius). The hot-dry season lasts from March to May (average 30-35 degree Celsius). From June to August is the rainy season, during which temperatures are relatively cool (average 22-30 degree Celsius). And from September to October is the cool-wet season (average 25-30 degree Celsius). At this time of year it rarely rains in the morning: most precipitation comes in the afternoon, and even then, only sporadically. Rainfall varies considerably from area to area. Whereas the seaward slopes of the south-west highlands (Kompong Som and Kampot provinces) receive more than 5,000 millimetres of rain per annum, the central lowlands average only about 1,400 millimetres.
