Existence of Mazovians as a tribe is rather hypothetical (according to book "Narodziny Międzymorza" by L. Moczulski - link below):
http://books.google.pl/books?id=FY_u2_TUiFoC&printsec=frontcover&hl=pl#v=onepage&q&f=false
Moczulski indicates that the idea that name of the province - "Mazovia" - comes from a tribe who allegedly lived there, is misleading.
The earliest known example of name "Mazovia" (describing a region, not a peoples) is from the late 11th century.
There are other theories about the origins of the name of this province. For example it could originate from the old term "mazia" or "maź" (which is a type of clay soil that is widespread in many parts of Mazovia, for example near Płock). Another theory is that it comes from rebellious cup-bearer of Polish duke Mieszko II and governor of this province, a certain Masław or Miecław (Latin: Meczzlavus):
http://en.wikipedia.org/wiki/Miecław
Initially Meczzlavus was a cup-bearer of Mieszko II and the governor of Masovia. However, an internal crisis and a
pagan reaction led to the exile of Mieszko II and rule of
Bezprym. This weakened the Piast overlordship over Masovia.
Next theory is that it originated from a personal name Mazoch or Mazos (who could be e.g. another Piast governor of the region):

Mazoch is still a common West Slavic surname - for example this Czech guy:
http://en.wikipedia.org/wiki/Jan_Mazoch
To me the theory that name Mazovia comes from ground (soil) type widespread in this region - mazia / maź - is convincing.
Of course it as well is possible (but how probable?) that there was a tribe who named themselves (or others named them - once again this exonym / endonym issue?) after that type of ground where they lived (mazia / maź), and later the region was called after them - not directly after mazia. There are, however, no any decisive proofs that Mazovians ever existed as a tribal identity of people who lived in that area.

Sile:
Mazovians had their own lands for 400 Hundreds year
What separate land ??? Those were Polish duchies ruled by the same family, Polish Piast dynasty. Moreover - as I wrote before -, Płock - which is in Mazovia - was the capital of Poland during the reigns of Władysław Herman and Bolesław Krzywousty (1079 - 1138).
Old prussians kept their langauge for over a 1000 years
No, only for about 500 years since the conquest (last speakers of Old Prussian ceased to exist in the 1700s).
Most of the germans settled in coastal trading cities and set up burgher system excluding any polish people from joining. A reason for the later teutonic-polish wars
In Konigsberg at one point Poles were 30% of inhabitants (but that was in times when Ducal Prussia was a vassal state of Poland).
But I have figures for ethnic groups in other Teutonic Order's cities before (in the Middle Ages) and no of them was fully German:
Thorn (Torun) years ca. 1380-1400: Poles were 6,5% in the centre of the city and 23% in the suburbs
Thorn (Torun) years ca. 1450-1470: Poles were 23% in the centre of the city and 50% in the suburbs
Kulm (Chełmno) years ca. 1380-1400: Poles were 10% in the centre of the city and 30% in the suburbs
Kulm (Chełmno) years ca. 1450-1470: Poles were 27% in the centre of the city and 52% in the suburbs
Löbenicht (New City Konigsberg) year ca. 1450 plus (the second half of the 15th century) - 42% Germans, 40% Old Prussians, 9% Lithuanians and Tatars, 7% Poles, Czechs, Latvians and Livonians, 2% Scandinavians (mostly Danes and Swedes I guess).
And in the 16th to 17th centuries, when Ducal Prussia was Polish subject, Poles were even 30% of inhabitants of Konigsberg.

On base of language Obodrites or Slovaks could have been included as Polish but they never were.
Slovak language is much more closely related to Czech than to Polish.
Austrian and Germans speak same language and yet they have their own national identity.
Austrian national identity is the product of Prussian-Austrian rivalry in the 19th century, later strengthened by the result of WW2.
Anyway - you should rather be wondering why do all Germans have the same national identity (despite being united as late as 1871, after centuries of "Flickenteppich").
Do you really mean there was a tribe without a leader? There are no records, so they didn't exist?
What I mean is that maybe there was no any tribe, but a number of smaller clans / families, who lived throughout the region.
No wonder Poland had 5 time less folks per sq km than Holy Roman Empire.
Poland had 4 - 5 folks per sq km around year 1000 (though according to some scholars, even more).
The Holy Roman Empire certainly did not have 20 - 25 folks per sq km at that time (5 x 4 / 5 = 20 / 25).
Probably the HRE had around 2 times (at the most 2,5 - 3 times) more folks per sq km than Poland, but certainly not 5 times more.
One war every 25 years or so.
Between years ca. 1350 and ca. 1650 (three centuries) there were no any major wars in the core of Polish territory.
Sure, Poland fought wars in that period, but they were fought in borderland regions (like Ukraine, Livonia, Prussia) or in foreign land.
