As mentioned from 3200 to 539 BC, what was to become Lebanon was part of Phoenicia. So its ethnicity is not Muslim or Arabs but a sea faring people on the coast in northern Canaan. As mentioned the cities of Tyre, Sidon and Byblos were city States and Kingdoms from which most Lebanese come from. Evidence shows Byblos is one of the oldest citiess in Lebanon.
These cities were then incorporated into the Persian Achaemenid Empire and then became part of Alexander the Greats Empire in 332 BC. The region was then split into provinces under the Roman Empire Coele Syria and Phoenice, the latter which the land of present-day Lebanon was a part of.
This is where Mount Lebanon comes in with a hermit named Maron who established the Christian Maronites who moved to the mountains to escape persecution from the Romans. Then comes the Muslims in the 7th century when they conquered Syria including parts of modern day Lebanon around the same time they conquered Jersusalem. They then took control of parts of Mount Lebanon in the 980's which resulted in the Druze religion a branch of Sharia Islam around the 11th century.
The cities of Sidon, Tyre, Acre, Tripoli, Beirut, and others were administered by the Muslim Caliph and absorbed into Arab culture. The Franks Crusades reclaim the former Byzantine Christian territories and establish the County of Tripoli as Roman Catholic Christian states along the coast for a couple of centuries and then it comes back under Muslim control with the conquest by the Mamluks.
Lebanon became part of the Ottoman Empire in 1516 and the area was organized into provinces: Northern and Southern Mount Lebanon, Tripoli, Baalbek and Beqaa Valley, and Jabal Amil. The Druze ruled southern Mount Lebanon until the civila war with the Maronites wherre around 10,000 Christians were slaughtered. Shortly afterwards, the Emirate of Mount Lebanon, which lasted about 400 years, was replaced by the Mount Lebanon Mutasarrifate, as a result of a European-Ottoman treaty called the Règlement in 1861.
After 1861 there existed an autonomous Mount Lebanon with a Christian mutasarrıf, which had been created as a homeland for the Maroni under European diplomatic pressure following the 1860 massacres. As a result Mount Lebanon was split into two parts one under the Maronite and the other the Druze. But certainly the Maronite has been there far longer.
The Maronite Catholics and the Druze founded modern Lebanon in the early eighteenth century, through the ruling and social system known as the "Maronite-Druze dualism" in Mount Lebanon Mutasarrifate.
On September 1, 1920, Greater Lebanon, or Grand Liban, was officially established under French control as a League of Nations Mandate.
Greater Lebanon united the regions of Mount Lebanon, North Lebanon, South Lebanon, and the Bekaa, with Beirut as its designated capital.
This led to Lebanese independence in 1943.

I think this is the political rule you are talking about from Mount Lebanon. But as you can see there is a lot of history leading up to that point. Even then at certain stages we could say Lebanon was already a nation and Kingdom of sorts along the way when its cities were autonomous and regarded as States or Kingdoms even under occupation like Isreal.
It seems like Isreal the Muslims came in later and captured territory and then made the area Muslim despite there being a strong Christian presence and even rulers. Lebanon has a shared power structure it seems where Christians, Muslims and Orthodox Christians share power.
But to say that Mount Lebanon is the be all and end all of how Lebanon became a nation is only telling part of the story. In some ways it seems the Druze who emerged out of Sharia Islam as rulers were a minority and ruling as feudal families.
Yes but its cities were always there and these make up the majority of Lebanon. They still has a ruling system before this as KIngdoms and City States even under occupation ie
By the mid-14th century BC, the Phoenician city-states were considered "favored cities" to the Egyptians. Tyre, Sidon, Beirut, and Byblos were regarded as the most important. The Phoenicians had considerable autonomy.
Under the Persians the Phoenician area was later divided into four vassal kingdoms—Sidon, Tyre, Arwad, and Byblos—which were allowed considerable autonomy. Local Phoenician kings were allowed to remain in power and given the same rights as Persian satraps (governors).

It seems many nations were declared or not declared States, nations, or Kingdoms by conquering powers who either allowed them to exist with a degree of independence or as a vassal or completely subsuming them. Nations borders have often changed into what they are today.
First there is the bible, one of the best history books as well when it comes to verifying the Isrealites and other nations and rulers as well as archeological evidence for those times, places and people.
But there is plenty of evidence outside the bible for showing that the Hebrews and Isrealites were a nation of sorts.
Just off the top of my head I can think of one. King David Kingly line is acknowledged by the Pharoh Sennacherib with the Tel Dan Stele. So Isreal was big enough and powerful enough to be mentioned among other nations and Kingdoms by the Egyptians. King Davids city has been found down from the Temple mount.
Why is the Tel Dan Inscription regarded as the first historical evidence for King David? Learn how this discovery, referencing the “House of David,” reshaped debates about David’s historicity and the early kingdom of Judah.

There is also evidence of King Hezekiah defending Jerusalem against Sennacherib which shows Judah was a powerful Kingdom.
Now that so much attention is being focused on the new excavations around the Gihon Spring and Hezekiah’s Tunnel—which was built as a defense against a siege by the Assyrian leader Sennacherib—it may be time to look at the siege itself. Specifically, was there one attack in 701 B.C., or were...

Then theres the Amarna Letters from Canaanite cities under siege by the Isrealites to the Egyptian Pharoh asking for help. They speak of losing their cities and how Canaan as a whole was being lost to the Isrealites as part of becoming a nation. There are around 380 letters but here as some more interesting ones.
Amarna Letter EA144
Zimreddi, mayor of Sidon, informs pharaoh that all the nearby cities have been lost to the Hebrews.
Amarna Letter EA215
Bayawa begs pharaoh to send Yanhamu, an Egyptian ambassador or provincial overseer, to help within the year or the entire land of Canaan will be lost to the Hebrews.
Amarna Letter EA284
Shuwardata, mayor of Hebron, claims that all lands nearby have been captured by the Hebrews and that he alone is left.
Amarna Letter EA286
Abdi-Heba, mayor of Jerusalem, informs pharaoh that he is the last city mayor standing that hasn't been captured by the Hebrews.

The Pharohs also acknowledged the Isrealites as a nation or Kingdom.
Menepta stele
The Merneptah Stele (or Israel Stele) is an engraved stone slab which describes Pharaoh Merneptah’s military victories in 1207 b.c.e. The mention of Israel in this 3,200-year-old document suggests, at the time of its inscription, the nation of Israel was an established power and not a nomadic people who had just recently entered the land of Canaan.

Sennacherib’s Prism
An Assyrian artifact known as Sennacherib’s Prism, the king boasts: “As for Hezekiah, I shut him up like a caged bird in his royal city of Jerusalem.”

There are many more like this that mention the Isrealites as a nation and/or Kingdom in passing.
It seems to have been no ones city. I guess being in that location on the coast and at the border of a number of powers it has a checkered history compared to more central locations. But in the end it was the Isrealites who settled it being that it was on the edge of their established territory.
The Egyptian King Merneptah actually mentions taking Ashkelon and Gezer while claiming to have laid Isreal to waste, their seed no more. Which is obviously not the case because Isreal was still around. But it implies that Isreal as a destinct people growing in power within Canaan around 1200 BC.
IBSS - Biblical Archaeology - Evidence of the Exodus from Egypt
The Amarna Letter EA287 also refers to Ashkelon, Lachish and Gezer being allied to the Hebrews. So it seems that around that time (3,000 odd years ago) Ashkelon and other Canaan cities were becoming part of the Isrealites.
